What players say

Players describe Cozy Aquarium as more of a diorama builder than a fish game, since fish don't need care and there is no breeding. The appeal is the massive number of decor props, though some find them mismatched or surreal. The integrated pomodoro timer and to-do list are quirky extras, but some players report the game crashing on launch or never loading.
