Of the art, I only brought in the fork, the hat, and the seed. The rest is made by hand. I wasn't really thinking much about lighting on the rocks, since I was just focusing on making a tilemap that didn't look awful. Overall, yeah, the art is super rushed and non-cohesive. That's mainly because I figured iterating on gameplay elements was more important than making a cohesive art style. The art process was pretty literally: start making it and only redo it if it looks awful. Originally, the setting was to be different per level, but no time ^.^, so rocks.
There actually is a built-in reset. If you hit esc or start on a controller, it brings up a menu to restart the level or quit. I understand that in game jams, you don't assume normal controls stuff is true, so I get why you didn't find it.
Thanks for the input and letting us know about bugs :).
