Nice Job! I got stuck on one of the levels in world 0 where you had to jump on top of 4 toasts. I felt like the jump could have been a tiny bit higher so that it was easier to get on top of the 4 toast stack, because I would not jump high enough over and over and then when I finally did I would go right into the red-block and have to restart the level. Also you cant jump while moving into a burnt toast(not sure if this is on purpose) I'm glad you had two more worlds to play thought though because the new mechanics added in those were all really nice. The pacing/level design in general was really good, to me it felt you introduced new mechanics at the perfects times!
