How it feels

a deceptively cute and methodical rat-breeding sim where you manage genetics, competitions, and an ever-growing colony with a light, mellow pace.

What players say

Players praise the realistic genetics and COI system, but some find the level-gated breeding grindy. Many want better rat organization and more to do, like buying supplies.
