Thanks a lot. Yes the idea was to stay minimalist. This is good feedback about the doc I could put that on the itch page and in the readme.
Some good ideas there. The ability to destroy enemies I'm not sure but what is very good is the "glue" idea. This would allow the player to move objects. So yeah a movable color. You can use it to block enemies or change their path, destroy a barrier (maybe). But also it could block yourself if you don't play it right. Could open more puzzle possibilities to the game. Definitively something I will think about :)
