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.

Fun characters and fun boss fights in what might be a bit of a overconvoluted story at times, but I still had a great time. Just a fair warning, if you expect loads of boss fights you'll be dissapointed. More story, especially if you do all the side quests, than bossfights. But all the bossfights were great
Bittersweet Birthday es un juego narrativo con mecánicas de combate que apenas se utilizan a lo largo del juego pero su fuerte es su historia y cómo ésta se desarrolla. Básicamente eres un niño que despierta en la celda de un complejo científico vacío y no recuerdas absolutamente nada, ni siquiera quien eres y a partir de ahí se desarrolla una historia de CIENCIA ficción, resaltando la palabra ciencia, que aquí no hay etés ni nada similar, donde iremos conociendo a personajes y saltando entre diferentes recuerdos que no tienes claro si son reales o no. Es un juego para tomárselo con calma que no está nada mal.
It's fun, the boss fights are challenging but fair and interesting. Outside of the boss fights, the characters and the world seem charming and wholesome, but it can sometimes feel like it takes a while between the action.
Una especie de aventura de accion narrada como novela visual adaptativa con peleas de por medio, esto implica que tiene un elemento mas fuerte como novela que como juego de accion, es decir, cuenta la historia y en medio hay peleas, y son pocas, pero como el fuerte es la historia, lo hacen demasiado bien y siento que hay secretos que no se han descubierto porque desgraciadamente no tiene comunidad como tal, pero es una muy buena experiencia que deben de probar.
Unforgetable experience with "layers" of storytelling and so many plottwists. if you liked for example omoris story which in some sense is a bit similar. Be ready to not understand anything 90% of the time. 9/10 would recommend
A fun game with great visuals and an enthralling story
Essentially, it's a game with captivating art and story. The fights are tremendous, the puzzles are balanced so they're not too tedious, and the story can be heavy at times, but it invites you to keep reading. This kind of game, where you can see the love that went into it, is what encourages support for indie games. Don't expect constant action, is not that kind of game, but when the crucial moments arrive: it's totally worth it. It's a fun game, sometimes you get frustrated, but the satisfaction at the end it's unique.
This games story is fantastic, it has so many twists and turns its really hard to guess whats gonna come next but nothing comes off as forced or arbitrary. The gameplay is great too but the focus of the game is definitely the story, there are only 9 fights and there are some pretty large gaps between fights especially if your trying to see everything which brings me to my only complaint (other then a few typos here and there) and that is the pacing. especially towards the end of the game there is so much dialogue and little to no gameplay, i am personally fine with this but if your the kind of person who prefers gameplay over story this probably isnt for you.
Very entertaining game with some pitfalls. Mainly wasnt a fan of having to spam talk to a bunch of npc till i figured out how to progress certain side missions. But i found the combat fun and the story enjoyable albeit confusing. All the way up to the end i definitely felt like Rocc
holy peak so glad I backed this game
