[b] Particle Hearts [/b] is a mixture of walking sim, platforming, puzzle, adventure, and exploration. At first, I thought it was just going to be a game like [url=https://steamcommunity.com/id/janner66/recommended/1213700?snr=1_5_9__402] Spirit of the North [/url] or [url=https://steamcommunity.com/id/janner66/recommended/563840?snr=1_5_9__402] Lost Ember [/url] with mostly exploration and a few light puzzles, but I was pleasantly surprised by how in depth it was and would rank this among the best I have played of this genre. The visuals are gorgeous, even if they are a little migraine inducing, and the music is very immersive and moving. The story was a lot more understandable and fleshed out than most games of this kind are and I really enjoyed the whole experience. The first thing that grabs you about the game is its visuals. Exploring a world made of particles and watching them sway in the breeze or trail off the character when he runs is really neat and impressive, and there are loads of times in the game when you will be reaching for the screenshot button. In conjunction with the orchestral sound track full of tense and dramatic moments it really is a feast for the eyes and ears, and there is an eerie atmosphere that keeps you on edge all the time. However, there is more to this game than just the way it looks and sounds. https://steamcommunity.com/sharedfiles/filedetails/?id=3560451076 The game lets you explore quite a lot and gives you the freedom to run around wherever you want. The areas do get more expansive as you progress and some of the later levels can be quite large. It can be easy to go around in circles looking to advance but each level usually contains the same mission which is to find the ten memories scattered around and to complete the three challenge levels. The story is told through eight chapters and each of the ten memories gives you a brief outline of the story. It doesn’t matter what order you find them, but if you do miss any, then you will miss out on the story, and the game will let you advance without finding them, so if you want to experience the whole story, and I would advise you to do so, then make sure you find them before completing the level. Even though each memory is just a brief paragraph of text, the combination of cut scenes and text actually provides quite a deep and emotional story which I found very interesting. The challenge levels start off very easy and I thought this pattern was going to continue, but in some of the later levels, the platforming and puzzles are quite difficult and I could envisage this being too difficult for some. These levels must be completed for you to advance so they are a potential roadblock for any further progress. Hopefully, there will be walkthroughs provided later but there are some quite tricky platforming sections also which send you back to the start of the puzzle area to repeat if you die, and this did cause a bit of frustration, but they’re not so difficult that it doesn’t urge you to keep trying until you succeed. https://steamcommunity.com/sharedfiles/filedetails/?id=3560451365 There are some action sequences during the game too, mostly to avoid the lunging attacks of the wolves which are trying to kill you. You have a boost to dodge attacks, plus during the game you will acquire two more special abilities in the form of particle disintegration, which allows you to move through objects and avoid being killed, and a burst of energy which can distinguish the wolves outright. There are cooldowns for these abilities though, and when you use the particle disintegration it can take a while for your meter to fill back up, and the game loves making you disintegrate through an object into a pen of wolves and have you frantically running around until your meter fills up again. The camera can be a bit annoying in these situations because it never seems fast enough to catch up with your sudden movements, but once a wolf has been killed it doesn’t respawn so it’s not too much of a hassle. [h1]🍳Conclusion🍳[/h1] [quote][h2][b] Particle Hearts[/b] was a fun game to play with some very impressive visuals and sound but it is not as chilled and relaxed as you might think. There are definitely areas which could potentially have you stuck and unable to progress because of difficult platforming or tricky puzzles. For some, this might be a good selling point but for others it might leave you worried. Personally, I really enjoyed the injection of pace and difficulty in some areas. Usually, these types of games are a little stale and predictable but Particle Hearts will play with your emotions as well as test your skills which I found to be a welcome change. The game lasts around ten hours if you want to try and get as much out of it as you can. There are various achievements and a chapter select for you to mop them up later. I would definitely recommend this to anyone looking for an exciting walking sim. [/h2][/quote] [quote]Thank you for reading my review.

A GEM THAT'S NOT TO BE MISSED! What initially drew me to Particle Hearts was the gorgeous art style. It looks like nothing else out there, and that’s a huge achievement in the indie game space these days. What won me over was the gameplay. You explore this beautiful world and solve puzzles using abilities you unlock throughout your travels. There’s also a story to unravel by collecting wind chimes and gathering the messages they hold, as you learn what happened to this world. The game has a very lonely, tranquil, and zen vibe. It reminds me of ICO, Shadow of the Colossus, Journey, and even Breath of the Wild at times. You can relax into the game and explore at your leisure. The music also matches the feeling perfectly. This is an indie gem for sure and one that’s not to be missed by fans of both exploration and puzzles.
Primarily played on PS5 at launch but picked up again on Steam to have ready for Steam Deck. Steam Next Demo ran perfectly on Steam Deck which is where I'll play the Steam version on. Beautiful game with a good soundtrack, enjoyable puzzling platforming style game that wears its Team ICO inspiration well. Game had more platforming than I was anticipated which was very welcoming to me as I love me some good platforming. Very nicely told story that makes good use of collectibles to help augment the proceedings (plus they are well placed so they aren't a laborious treasure hunt every level. Very much enjoyed my time with it on PS5 (got Platinum trophy in around 8 hours according to PSN) and will replay on Steam Deck. I recommend as its both a gorgeous game but also plays well, runs well and is just a nice time. Edit Update (8/28): Just wanted to quick update after playing first level on Steam Deck. It ran perfectly just as the Steam Next Fest demo did. Had the 2nd level of stats up to see pretty steady 60fps with zero changes made to Steam Deck's battery settings. Should see good battery life as I started at like 27% and only dropped 9% in the span of playing the first level. Def recommended and esp for Steam Deck.
Sort of pretty, although the animation work is rigid. The puzzle rooms are OK, but that's all the game is between long stretches of boring exploration, and there's so much WAITING for platforms and ability refreshes and full-room resets if you fall into the void. The big demon you're feeding is the coolest part of the game, very mysterious and compelling. But there's a lot of game stretched out ahead of me and very little fun to be found, so I'm quitting in the third area. Looks like I'm not alone, as only something like 15% of players have made it this far. My suggestion for the devs is to narrow your ambition on your next project. If this game were 3 dense areas with a better animated protagonist, I think the vision would shine a lot brighter.
Not a bad little game. Art is beautiful matched with an equally beautiful soundtrack. I didn't find the puzzles very difficult but I liked the execution of them. Puzzles included some platforming, memorization, and timing with some incorporation of skills you acquire through the story, reminiscent of Breath of the Wild or Fenyx Rising puzzle dungeons. Story was pretty bare bones but had a few thought provoking moments. I would recommend to someone that likes walking sims, light puzzles, good music, and nice environments to look at.
Really enjoyed art-style, game-play, and think that DEVs did a amazing job for something unique. Keep up the great work. This video will contain the whole first chapter of game with collectibles. Gameplay Showcase: https://youtu.be/6JpJANbLTi0
I got the platinum trophy on the PS5 and now am working on all achievements on Steam. You can tell a lot of love and care went into this game and there was a lot of passion behind it. The visual style is beautiful, the world is fun to explore, the music is amazing, and the story is mysterious and compelling. Make sure you get all the chimes in each level to really get all you can out of the story. Highly recommended!
Ich habe das Spiel viel zu günstig in einem Bundle gefunden und hab's mal angetestet. Man kann mit so einem Spiel sehr viel falsch machen. Hier ist das aber nicht passiert. Die beruhigende Optik , das ausgewogene Gameplay und der Storyansatz ohne zu viel zu verraten ist sehr gelungen. Eines der schönsten Spiele die ich in letzter Zeit gespielt habe und ich spiele viele an , da ich ein Testformat auf YT hab

Particle Hearts is a meditative and emotionally resonant puzzle-platformer that invites players into a luminous, dreamlike world built entirely out of shifting particles and ambient storytelling. Developed by Underwater Fire and published by First Break Labs, the game is less concerned with traditional platforming conventions and more focused on crafting a surreal and atmospheric experience that emphasizes introspection, discovery, and visual poetry. It’s a game that speaks softly, offering subtle narrative fragments and abstract challenges in a setting that constantly feels like it’s on the edge of unraveling or reforming into something new. At the heart of the game is the Drifter, a mysterious horned figure who awakens in a quiet, alien world with no memory of their past. There’s no exposition dump or guided tutorial—just an open landscape and the vague sense that something has been lost or forgotten. As players begin to explore, the world opens up through interconnected biomes, each with its own identity, ambient soundscape, and shifting particle environments. Rather than being driven by a central plotline, the game uses scattered memory fragments—wind chimes hidden throughout the world—to hint at the Drifter’s past and the strange cycle they seem trapped within. These fragments are entirely optional, making the storytelling feel both intimate and elusive, rewarding curiosity rather than checklist completion. Gameplay unfolds in a slow, deliberate rhythm. Movement is light and floaty, encouraging the player to drift rather than dash. The Drifter’s primary abilities—gliding, dashing, and eventually manipulating aspects of the environment—are introduced organically as the game progresses. Central to progression are “Figment Gates,” which serve as self-contained puzzle chambers scattered throughout the world. These gates shift the game’s mechanics in subtle and sometimes surprising ways, bending gravity, warping spatial logic, or altering how objects interact. While none of the puzzles are especially difficult, they’re often elegant in design and deliver a quiet sense of accomplishment. The emphasis is never on challenge, but rather on flow—each gate feels like another piece of the world’s language you’re learning to interpret. Visually, Particle Hearts is a standout achievement. The entire game is rendered using a particle-based system that gives every surface, object, and creature a shimmering, ephemeral quality. It feels like you’re wandering through a world made of stardust and memory. The environments pulse and ripple in response to your presence, creating an almost hypnotic sense of immersion. At times, the sheer beauty of the visuals can distract from navigation, as it’s not always immediately clear what is solid terrain or what’s decorative, but this ambiguity often feels intentional, reinforcing the sense that the world exists in a liminal state between form and dissolution. The audio design complements the visuals with understated brilliance. There’s no bombastic score or dialogue to direct your experience—just ambient tones, soft environmental sounds, and occasional melodic cues that mark discoveries or shifts in space. These elements are layered carefully, drawing attention to important environmental details while also enhancing the game’s overall mood. It’s a game that benefits greatly from headphones, where even the faintest chime or rustle of particles can feel meaningful. Despite its many strengths, Particle Hearts isn’t for everyone. Its slow pace, minimalistic storytelling, and light-touch mechanics may not resonate with players who seek tight platforming, structured narratives, or high-stakes gameplay. Some may find the floaty movement imprecise, particularly during more intricate platforming sequences. There’s also a sense of repetition in some later sections, where puzzle design doesn’t evolve dramatically and exploration begins to rely too heavily on backtracking through previously visited biomes. Yet these shortcomings don’t diminish the game’s core experience for those willing to meet it on its own terms. Particle Hearts is a quiet, beautiful, and emotionally evocative journey that prioritizes feeling over function. It’s about wandering through a broken world, piecing together moments of clarity, and accepting that not every question needs a clear answer. For players who appreciate games like Journey, GRIS, or Rain World—titles that use aesthetic and atmosphere as narrative tools—this is a game well worth exploring. It doesn’t demand your attention; it gently earns it, one shimmering particle at a time. Rating: 8/10
