Pretty clever tutorial. That worked quite well for me. Never managed to fart, though. The level design of the main level is pretty mean especially due to the giant collider of the player character. I'd make that one quite a bit smaller so you can't eat stuff that's already behind you.
Game looks great, has cute graphics and cute music. Definitely quite sympathetic.
For some reason I didn't get any food when eating pizza. Didn't quite understand why. That was probably explained in the tutorial, but I probably missed it and it feels kind of weird to eat a pizza without seeing the resource with the pizza icon increase.
Cool game. Hope you're proud and had fun. :)
