About

You wake up in a strange facility with no recollection of who you are or how you got there. That is, until a voice calling themselves ‘Ada’ on the other end of an intercom warns you that you’re being hunted, and promises to help you escape.
Bittersweet Birthday is a story-driven action-adventure game where every fight is personal, every victory hard-earned, and every clue a step towards uncovering the truth lying somewhere inside the miasma of mysteries.

Each encounter is a one-on-one showdown with one of your nemeses. Read your enemy, master their rhythm, and adapt to their patterns that blend Souls-like precision with bullet-hell chaos. Punch, kick, block, dodge and parry your way through multiple phases that feel like a final boss each time.
Tweak the challenge to your liking through the Memory system. Memories are gameplay modifiers directly tied to the character’s pasts. They can make fights easier or harder, but never trivial.

Between fights, catch your breath in a vibrant village full of strange and endearing characters. Complete side quests, dig into local mysteries, and enjoy a surprising amount of heartfelt (and often ridiculous) downtime.
Try your hand at darts! Or well… I guess darts are partially used, at least.
Rock, paper, scissors – fighting game edition!!
Hunt down all 48 Gachapon collectibles, each one of the cool, cute, or creepy kind!
Hand-drawn pixel art and detailed backgrounds bring every memory and location to life.

The upsides: - Interesting story that is deeper than at first glance. I really didn't expect to get hit with discourse over the meaning of life or what life even is. - Heaps of flavor text. If you're the type to examine things or talk to characters multiple times in a row to see if they say anything different, or intentionally going the wrong way, this is for you. You could tell the devs had a lot of fun writing the game. - Engaging boss fights and game mechanics, with variable difficulty based on your preferred playstyle. Beneficial Memories costing slots and detrimental Memories giving slots is a good system to work with. - Outside of the tense bosses, the "adventure game" half of it is nice and cozy. Feels mundanely pointless until you realize that it's not pointless at all. At least not in the grand scheme of things or not how you'd expect. - A dramatic mystery that keeps building, asking questions and giving answers, and it all comes together at the end. I kept wondering aloud, "We never did find out about X, or learn who Y was..." and the game answered those questions in a satisfactory way. ...Except I don't think that this one gag character guy who sleeps the whole day and disappears from his house at night got any on-screen explanation but this isn't about him. - Fun sense of humor, very shounen manga-inspired. Even right down to the way it's written feels like it's taking inspiration from how shounen mangaka write, with introducing terms and explaining them later. Devs appear to be big fans of HxH and OP, huh. - Great implementation of backer content that doesn't break immersion (i.e. no zone that only exists for backer content). I was genuinely surprised that many NPCs added by backers fit so fluidly across side content, across the story, etc. They were incorporated very well to feel like they're really SUPPOSED to be there to begin with. The downsides - Surprising difficulty spike at the first boss that peters out as you go, to the point I was surprised I didn't die to some battles later on. But YMMV on that one. - Some pretty easily missable content (WHY) - About the flavor text, there's no indication of whether or not talking to an NPC or interacting with the environment will give new dialogue. And this is a game where you're kind of expected to do that to exhaust all the dialogue and advance side quests and such. - Adventure game half, specifically the "morning" segment, actually wraps up too early. - Could use a bit more English proofreading. Lots of "it's" vs. "its" errors, but it's still very readable nonetheless. - I'll be real, the last third of it dragged in pacing to a crawl with heaps of exposition and lore dumps. Even at the 11th hour, new terms were cropping up and having to be explained. Changed genres to visual novel at that point. I had to set it down one night at that leg of the game, as it kept giving me new information without engaging me through anything like puzzles or battles. Some controllable segments, sure, but just still story-story-story-story. Then I picked it back up the next day and I STILL had a good 2 hours until the next boss fight. The FINAL final stretch had a HUGE cutscene, like maybe 30 minutes before the final boss battle as well, and I was hit with the final boss at like 1 am. Not to say I was disinterested, but there was such minimal interaction at that point with characters just talking to each other and going from point A to point B that you could get worn out at the finish line if you are not in it for the story. - Genter, that guy with the dirty laundry problem, is never getting that help, huh?
Not the worst combat, but hugely disappointed in the story. The town was fine, but difficult to find the right npcs for side quests. The rest in a mess: A lot of things happen, with barely any rhyme or reason, with 5 hours later a terrible, hand-of-the-author explanation like [spoiler]Rocc got convinced he had to die by his brother's hand because he got hit by Ada's beam of "undeniable truth"[/spoiler]. A lot of gameplay is just following the only available path. And even that abruptly stops in the second half (after [spoiler]My Turn[/spoiler]) where there are multiple ten minute long sequences of dialogue where barely anyone makes a choice. And these sequences are made even more unbearable by every thing having a short pause, making it a slug even if you mash through all the dialogue. Can't recommend.
Just started playing and I’m already all in… you don’t just play the fights, you feel them. Facing Rocc wrecked me a few times, but man, finally getting through felt glorious. The story’s still unfolding like a twisted maze — bouncing between flashes of another reality and the panic of escaping the facility. I can’t put the controller down. The vibe is just perfect.
Definitely an interesting case. The battles are good and well thought out for the most part...but this isn't the main focus of the game, it's mostly story based. And it DO have a great story behind, many good plot points well used. However, it's a slow burn, it start slowly, and the last third is REALLY overly wordy, it love to hear itself talk...which is a shame because the ingredient of a good plot and good characters are clearly here, i just wish it was better paced. It's still worth a look, there's clearly good care put behind the game, just be prepared for alot of reading.
So, this game surprised me in the best way. At first you think it’s just another indie action game, and then BOOM, you’re getting chased, you’re confused, and suddenly you’re stuck in these wild multiphase boss fights where everything on the screen wants you dead. And honestly? It’s fun. You actually have to learn the patterns, dodge like your life depends on it, and land combos at just the right moment. If you like emotional stories mixed with tough combat and charming pixel art, this game is worth keeping on your radar.
The game has some things going for it - graphically, sound-wise, and functionally, it's fine, but holy cow is it wordy af. Waaaaay too much dialogue in between sequences. Please make me care about the characters first. If I wanted a novel I would have grabbed a book.
A striking story driven game with immersive exploration and strong atmosphere, but its steep combat difficulty and limited guidance can make progress challenging for many players. The game begins with a short and strange vision. You see a birthday cake with candles, and three unsettling figures standing around it while staring directly at you. Nothing is explained and the scene ends almost immediately. You then wake up in an unknown room inside a facility. You do not know who you are, how you arrived here, or what is happening. A voice comes through speakers and introduces herself as Ada. She tells you to move forward and follow her instructions. Since you have no other information, you decide to listen. The facility looks cold and empty. The rooms and hallways contain little more than metal walls, flickering lights, and abandoned equipment. There is no sign of life, but the place also does not feel completely inactive. After you begin exploring, you soon encounter something that looks exactly like one of the figures from your earlier vision. It immediately attacks, and this moment introduces the main combat mechanics of the game. Combat consists of movement, defense, and offense. Offense includes a normal attack and a heavy attack. These two attacks do what their names suggest and do not involve complicated input combinations. Defense consists of dodging and parrying. The important part is timing. If you dodge or parry at the exact moment an enemy attack is about to connect, you recover stamina. If the timing is off by even a small amount, you avoid damage but gain no stamina. Stamina is important because it is used for almost everything. You have a good amount of it, but it refills slowly. Dodging repeatedly drains stamina quickly, so careless use can leave you unable to avoid important attacks. Attacking also uses stamina, especially the heavy attack. When you have enough stamina available, you can attack repeatedly without being forced to stop, which allows for fast strings of hits. Enemies have a hidden focus metes. When they take enough damage, their focus breaks. At that moment, the enemy becomes vulnerable and can be knocked down, but only if you hit with a heavy attack during a short moment when the enemy glows red. This red interval appears in cycles, and one reliable way to trigger it is to intercept an enemy attack. When you knock an enemy down, you get a short period where you can deliver several free hits before the enemy stands again and regains focus. Every battle in this game is a boss fight. There are no regular enemies. Each boss has several phases, and every phase adds new attack patterns. Many of these attacks are fast and unpredictable. Learning the timing takes patience, and the game expects you to fail while learning. Your character has a large amount of health and receives partial healing after each phase, but this does not remove the need to block or dodge correctly. If you ignore the defensive mechanics, you will eventually lose. Between fights, you explore the facility and examine objects in different rooms. When you are close to something you can interact with, an exclamation mark appears. Some of these interactions only show a short comment. Others unlock memories. These memories form an important system that affects battles. Memories act as modifiers. Some help you by giving advantages such as reduced damage from attacks or healing after dealing a certain amount of damage to enemies. Other memories introduce disadvantages. For example, some make you begin battles with reduced health. Unlike positive memories, negative memories do not require any orbs to equip. In fact, equipping a negative memory increases the number of orbs you can use, which allows you to equip more positive ones. This creates a system where you can choose to take a disadvantage to gain more advantages in return. Once a fight begins, you cannot change your selected memories until it is over. After the first boss fight, the environment changes completely. Instead of the cold and empty facility, you find yourself in a bright and friendly village. This village contains several places such as a bookstore, a market, a pub where you can play darts, and other small buildings. Many characters live here and you can talk to all of them. Much of the time in this area is spent reading dialogue, exploring buildings, and advancing the story through conversations. Some characters have many lines of dialogue, and the game does not mark which characters are important. Because of this, players who want to avoid missing content will likely speak to everyone. Some characters request items. When this happens, your inventory opens automatically so you can select the correct item. Items are obtained by exploring the village or by talking to people. There is also a small collectible system that uses a gacha machine. You can buy gacha rewards with coins that sparkle in the environment or that you receive from characters. Despite the friendly atmosphere, something in the village feels slightly off. Sometimes small visual glitches appear on the screen, and some characters become transparent. Eventually, the game returns you to the facility. After this point, the story moves back and forth between the two locations. Sometimes this transition happens automatically, other times the game asks whether you want to continue. The facility gives you freedom to revisit old rooms. The village, however, feels like it could contain missable content. Fortunately, you can return to the village by finding a sleeping spot in the facility. You can also choose whether to visit the village during the day or during the night. Dialogue changes depending on the time, and some items and optional activities appear only during one or the other. This system ensures that you do not permanently miss collectibles or optional interactions, such as darts or certain challenges. The strongest part of the game is its story. It is well presented and offers several interesting ideas. The gradual transition between the two worlds, and the way the story uses these shifts, creates a unique atmosphere. However, many players might not see the full story because of the combat difficulty. The game offers no easy mode and no method to brute force progress. Perfect timing on dodges and parries is required, especially in later fights. The first boss is manageable, but the second boss already shows how demanding the game will become. Although there are only a few fights, each one can become a major obstacle. This difficulty may cause frustration for players who are more interested in the narrative than in challenging reaction based combat. Update: I was informed by the developer that there is a memory that makes every hit deal small damage, which turns it into "story mode", so it's possible to experience everything without battles getting in the way. For players who enjoy demanding one on one opponents and precise timings, the game provides a rewarding experience supported by a strong narrative. For others, the difficulty may overshadow the story. If you have patience and a willingness to practice, the experience becomes worth the effort. The combination of exploration, memory collection, and intense battles creates a structure that stands out.

I had a consistently good time during my playthrough, so I'd definitely recommend this game. The highlight of the game is in the characters and writing. There's plenty of life and personality in the world of Bittersweet birthday and I'd be remiss not to mention the gorgeous pixel art. These elements carry the game. I tend to play more combat oriented RPGs, but the story was engaging enough to keep me playing during the slower moments. The term boss-stroll defines this game perfectly. I'd say my initial playthrough was about 15 hours and [b]maybe[/b] 2-3 of those were boss fights and puzzles. I also know that I didn't do myself any favors in that department by looking for absolutely every bit of side-content and dialogue. The gameplay loop consists of 1-2 hours of cutscenes and story progression in-between each boss fight, with side-content accessible during breaks in the story. The bosses were engaging, but not super difficult, as someone relatively familiar with action-combat. I played without memories, as suggested, and beat at least a few of the bosses on my first try. The rest took just a few more tries. The bosses felt intense and I could see someone less experienced struggling, especially with a few difficult memories turned on. My main critique would be that the pacing can feel slow towards the second half of the story. After [spoiler]the time reset shenanigans[/spoiler] and once the story progression was no longer just focused on the build-up to the next boss, the bosses felt a bit like gates to more story, instead of fun breaks. I think this was because I beat them relatively quickly before going right back to another couple hours of story. Admittedly, I may have front-loaded the side-content by doing it as soon as it was accessible; so, I didn't have those as breaks from the main story for the final third of the game. I'd suggest that people take it a bit slower and do the side-content when they want a little breather from the story. I was worried about missing out on some content and unique-interactions but the game does a pretty good job about not letting you miss too much. I think a few more small QOL features would help, because I spent a lot of times checking NPCs for new dialogue, but it's clear that effort was put into that area. The games tries to communicate to the player their completion progress in diagetic ways, although it was sometimes still unclear to me. To summarize- Bittersweet Birthday is a fun and engaging game that looks gorgeous. However, it's heavily dominated by cutscenes and story segments that can slow down the pacing at times. The story was enough to keep me going, but I'd still have enjoyed a tighter experience a bit more. I'd recommend the game to people who like slow burn mysteries with unique characters and don't mind fighting a few bosses to see it.
战斗手感不错,难度也可以根据使用的记忆不同自由设置,既满足略微手残的玩家,也满足尝试高难挑战的玩家。剧情方面,故事后期逻辑自洽,该解释的都解释了,总体来说观感不错。人物的成长非常自然,[spoiler] Rocc一开始逃跑确实让我有些无语,但是也明白毕竟只是小孩子,[strike]而且凭借我的水平未必打不过对面,虽然没想到对面把我秒杀了[/strike] 后期Rocc虽然还是有些害怕,嘴上一直在说有多痛苦多痛苦,但还是努力去找自己的兄弟,也愿意直面自己的错误 [/spoiler] 总体来说,不错的游戏,就是感觉短了一点,结局之后还有些意犹未尽,感觉真的很想看些后日谈之类的东西,和村民聊聊天,[spoiler]姐弟相认后尴尬相处,特别是多来些主角和其他人的互动[/spoiler]之类的, [spoiler] 毕竟主角前期真的太没存在感了,虽然是有意为之,村民都很少直接和主角互动,主角还是太惨了,最后结局部分感受别人的关心的时候还是处于昏迷状态。[/spoiler] 遗憾遗憾。 总体来说,挺优秀的游戏,如果你喜欢像素风格并且想要一些交互感强的boss战斗,那我强烈推荐这款游戏。 会有dlc之类的吗?
