I didn't really know what to do for the cover image but I just thought mushrooms with motion blur would be hilarious. I'm actually aware of the generation behavior, originally I wasn't sure how to check every block to see if there was at least one good mushroom but I can certainly program that now. My original solution was the little button mushroom button in the bottom right which skips turns and I had actually forgotten about that until now. I'm really glad you like it though!
I-- wow, embarrassing, I didn't put two and two together and thought that clicking the button mushroom was just to go to the next bit of the tutorial. And I've come back multiple times to this game to de-stress throughout the jam's first week. Wow. Having the ability to skip turns does fix the no-good-mushroom issue, haha.
