gameplay24 positive mentions
grinding4 negative mentions
  • Extensive creativity and customization in building unique creatures using diverse and interacting cell types.
  • Deep and rewarding gameplay with emergent mechanics similar to Noita and Spore's cell stage, offering vast possibilities for experimentation and strategy.
  • Engaging roguelike elements with challenging combat, meaningful enemy variety, and an evolving ecosystem that keeps gameplay dynamic and replayable.
  • Steep learning curve and lack of clear tutorials or detailed cell explanations can frustrate new players and hinder experimentation.
  • Permadeath and absence of save points or checkpoints make progression punishing, leading to repetition and possible player frustration.
  • Control scheme and movement mechanics can feel clunky or unintuitive, diminishing player experience especially during critical moments.

  • gameplay

    66 mentions Positive Neutral Negative
    36% positive mentions, 59% neutral mentions, 5% negative mentions

    The gameplay offers a deeply complex and original creature-building system with mechanical and emergent roguelike elements, praised for its addictive experimentation and creative possibilities. However, its steep learning curve, obtuse or incomplete mechanic explanations, punishing roguelike design, and lack of clear progression or biome variety can cause frustration and accessibility issues. Overall, while highly rewarding for players who enjoy mechanical depth and experimentation, the gameplay may feel at odds with its genre and inaccessible for those seeking more straightforward or forgiving experiences.

    • “Truly inspiring to see so many original fun ideas in one game between the gameplay and huge variety of cell types.”
    • “The building mechanics are incredibly complex and in-depth, and it's fun to just experiment and see what you can create with limited resources.”
    • “Even in its beta state, this is already one of the deepest, most mechanically complex games I have ever played.”
    • “I find a lot of very complicated mechanical parts that I can guess the purpose of but very little I can actually use to deal damage, then I reach what I assume is a boss and it effortlessly blows away the only means I have of dealing damage to it.”
    • “The creature creation mechanics are solid, but make for a sour experience with effort and creative expression getting wiped out by rogue-like single-life mechanics.”
    • “I can imagine if you take the time to learn what every cell does at a mechanical level (very hard to do since none of them very accurately explain how they work or what they do or when to use them) it would be an incredible time... but you basically need a PhD to wrap your head around when to use a transistor cell or a stem cell properly in a build.”

  • replayability

    8 mentions Positive Neutral Negative
    88% positive mentions, -1% neutral mentions, 13% negative mentions

    The game offers high replayability, driven by its creative sandbox mode, diverse creature mechanics, and roguelike elements that keep gameplay engaging and varied. While some users appreciate the depth and endless content, others note minor control limitations but still find it fun and replayable. Overall, the game encourages experimentation and strategic play, sustaining long-term interest.

    • “Very enjoyable game feels like it has endless content and is always replayable. The creation is fun to use even if the learning curve seems hard. I just use sandbox to study pre-made creatures to see how they work and workshop creatures to come up with new things and new ways to move parts.”
    • “Super replayable, super fun, and lets you get super creative.”
    • “The physics and various implementations of cells available makes for an incredible amount of replayability.”
    • “There is no replayability.”

  • humor

    5 mentions Positive Neutral Negative
    100% positive mentions, 0% neutral mentions, 0% negative mentions

    The game's humor is widely appreciated, especially for its hilarious and game-breaking builds, silly deaths, and unexpected creature shapes that add a lighthearted, entertaining element. While the humor shines through creative gameplay, reaching the funnier build stages can be challenging due to the game's difficulty.

    • “Amazing game if you like figuring out ways to make incredibly hilarious and gamebreaking builds.”
    • “It's also funny (but also a tad frustrating) to see a stupid or silly death.”
    • “Fun starts with interesting builds which are quite possible from the 3rd biome where you can actually find a lot of cells and cook up something very funny to play, but you get there rarely as the game is kinda challenging.”

  • music

    5 mentions Positive Neutral Negative
    60% positive mentions, 20% neutral mentions, 20% negative mentions

    The music in the game is consistently praised for being excellent, immersive, and expansive, perfectly complementing the gameplay and sound design. Users highlight the soundtrack as a standout feature, describing it as "fire" and essential to the overall experience.

    • “Lastly, the music is super good.”
    • “You're missing out on the greatest sporelike gameplay, sound design and soundtrack Steam has to offer.”
    • “Not to even mention the music, it's perfect and expansive, just as the game is.”
    • “Always a great game 10/10, wait I'm not done let me turn on my music right quick, I hate Spotify ads.”

  • grinding

    4 mentions Positive Neutral Negative
    0% positive mentions, 0% neutral mentions, 100% negative mentions

    Users find the grinding in the game tedious and sometimes unnecessarily prolonging the experience, particularly due to repetitive stages and extensive map scouting for XP and resources. Additionally, repetitive tasks like managing weapon upgrades and manual save file copying add to the sense of monotony.

    • “Which would not be a problem for me, I like Noita after all, but after that tedious stage right before, that 'f*ck you' hits really hard and makes the game unnecessarily longer to finish in my opinion.”
    • “Also, having to scout literally every corner of the map for XP and nodes feels a bit tedious, though I haven’t yet figured out a better solution for that.”
    • “I just find it tedious to place a few weapon cells that are going to immediately change after I get a massive group of cells in like 30 seconds after killing the same first enemy.”

  • graphics

    3 mentions Positive Neutral Negative
    100% positive mentions, 0% neutral mentions, 0% negative mentions

    Users praise the game's graphics for their unique and stunning artistic style, describing them as some of the most visually appealing they've seen in a long time. The combination of interesting cell types adds to the visual charm, complementing the engaging game mechanics.

    • “I love the graphic style and enjoy all the interesting cell type combinations.”
    • “Visuals: prettiest game I have seen in a long time.”
    • “Despite its small size, the game mechanics annihilate its simple yet stunning graphics.”

  • stability

    2 mentions Positive Neutral Negative
    50% positive mentions, 0% neutral mentions, 50% negative mentions

    The game generally runs well with good stability, though some glitches typical of a beta version are present. High CPU temperatures were also noted but did not significantly impact overall performance.
