The concept is cool and definitely unique but I think I've found a bug(?). My die gets damaged by itself. Either it's a bug or I am a tad bit too stoopid :D Overall I apreciate the submission.
The How to Play explains this but it doesn't seem to show on the submission page - just the main itch.io page!
You are meant to take damage from your own attacks so you have to kill enemies to heal it back :)
