Hey thanks for the awesome critiques, a good settings menu is on the way post-jam. I couldn't think of anything else for the mutants to do though, that's a problem I still have to figure out. They were coded to split their attention between attacking the player and eating plants, based on whichever food sauce caught there attention first during their wander path. Since the player still can't plant new food though I have that commented out. Once seeds are added though that behavior will be back.
I'll be sure to try out your game tomorrow, thanks!
