About this game

Game Features

Idle training, branching growth, and multi-ending storylines in one package.

A relaxing simulation you can enjoy during short breaks.

Evolution paths change based on your choices, leading to multiple unique endings.

A healing game at first glance, but with unsettling and dark undertones.

Cute visuals contrast with laboratory experiments, DNA extraction, and mysterious bad endings.

A Story for Thinkers

Each creature you raise generates a research report.
These reports make you reinterpret your actions and uncover what they truly mean.
If you enjoy hidden lore, mysteries, or piecing together fragmented stories, this game is for you.

Evolution Even While Idle

Time passes even when you are not playing.
Your specimen continues preparing for its next evolution stage.
When you return, you may find surprising changes waiting.
