Very fun game, but there is a bug I encountered after playing a bit where if all the colors were one, any other color pieces would not change the colors up, so I could not fight the engine overheat despite putting only the instructed color inside.
Are you sure you didn't have a perk that makes all tiles of the lowest count green? That perk has a fatal flaw of if you end up with full green board, and piece you place will result in 4 of it against 5 of green and all will then be green.
Sadly I didn't have enough time to fully polish the different skill options and add more. Maybe a post jam version of the game is in order...
