About the game

Grow a living fortress through an idle defense run

Idle Mutation Tower Defense is a single-player defense roguelite in a biopunk fantasy setting. The fortress attacks approaching monsters automatically, while the player collects resources and chooses organs that visibly change the tower and its combat abilities.

Survive as many waves as possible without allowing the monsters to destroy the living fortress. Temporary choices shape the current run, while permanent mutations support later attempts.
