  • Extremely creative and flexible creature building system with a large variety of cells and combinations allowing for unique and interesting builds.
  • Deep and complex mechanics reminiscent of Spore's cell stage and Noita's wand building system, providing a rewarding challenge for players who enjoy experimentation.
  • Fun ecosystem and enemy designs that use the same cell-based system, making encounters varied and engaging with high replayability.
  • Steep learning curve and punishing roguelike difficulty, including frequent instant deaths and lack of meta progression or save points, which can frustrate new or casual players.
  • Early game progression can feel slow and repetitive due to limited starting cells and the need to farm for useful cells, leading to potential grind and boredom.
  • Clunky and unintuitive controls with issues such as inconsistent input schemes, lack of proper tutorials or detailed cell descriptions, and poor gamepad support detract from the experience.

    The gameplay is highly praised for its deep, complex mechanics centered around creature building and electrical systems, offering a rewarding and addictive experience for players who enjoy experimentation and emergent gameplay. However, it can be punishing and difficult to grasp due to limited explanations and steep learning curves, making it less accessible for some. While the roguelike elements provide replayability, the gameplay loop sometimes feels arduous and unpolished, with certain mechanics clashing with genre expectations.

    • “Very in-depth mechanics with how voltage and electricity works.”
    • “Overall, it has basic RNG, interesting AI on enemies so you can't just cheese everything, interactive build combos, and a clear open-ended structure to really play with the mechanics of the game.”
    • “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.”
    • “Punishing gameplay isn't fun, and this gameplay is punishing not challenging.”
    • “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.”
    • “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

    The game offers high replayability through its extensive content, creative sandbox and workshop features, and varied gameplay systems like roguelike elements and physics-based mechanics. While some find the learning curve steep, the depth and freedom to experiment keep the experience fresh and engaging. A minor improvement suggested is customizable controls to enhance ability management.

    • “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.”
    • “Great replayability and depth.”
    • “The physics and various implementations of cells available makes for an incredible amount of replayability.”
    • “There is no replayability.”

    • “Amazing game if you like figuring out ways to make incredibly hilarious and game-breaking builds.”
    • “It's 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.”
  • grinding

    Players find the grinding in the game tedious and unnecessarily prolonging, especially during certain difficult stages and the repetitive task of scouting for experience and resources. Additionally, managing weapon upgrades and manual save copying add to the sense of tediousness.

    • “After the tedious stage right before, the 'f*ck you' hits really hard and makes the game unnecessarily longer to finish.”
    • “Having to scout literally every corner of the map for XP and nodes feels a bit tedious, though I haven’t figured out a better solution yet.”
    • “It's tedious to place a few weapon cells that immediately change after getting a massive group of cells in about 30 seconds after killing the same first enemy.”
