Amazing work on your game, the art and the character were very charming.
The controls were pretty weird, I found them too random to be predicted, especially on the toasters, I would most of the time just be flung downwards instead of to one of the sides if I tried to lean in one direction. The camera also didn't help. If just a tiny bit of the bread boy passed through a hole, even if I didn't fall down yet, the camera would just move places, and stay there until I restarted.
The checkpoint system really helped, but if you want to go the Getting Over It's route, you'll unfortunately have to get rid of it. The game would fit perfectly on the genre, but it's your call if you want to go that route. Congrats on the game!
