Yeah, I had had plans on trying to have it so you could pay in decayed tiles for different boosts, but didn’t have time for that in the end.
Given what time I did have, I was more focused on making sure the proc gen didn’t make things unwinnable.
We’ll see if I have a proper amount of time to come back to it (I’ve got other jams and ideas scheduled, especially 7DRL), but I do think the idea has legs.
