What Steam players say

Recent verbatim reviews from Steam — separate from playze.io community reviews below.

✦ AI summary

Players praise the game as an educational and fun experience with impressive graphics and engaging cell-defense mechanics. However, the difficulty balance is inconsistent, with level 4 being frustratingly hard until players discover the pause button exploit, which then makes it trivial. Players want more content, including additional levels and expansions featuring new pathogens and defensive mechanisms.

[h1] Nice game about learning how cells work. Build defensive mechanisms and protect your friend from pathogens. Need more balancing out though as level 4 is almost unbeatable. Also there's one strategy that gives you and edge. [/h1]
