The fact that you get bigger and it gets harder to hide is a super cool idea. But I don't really get why you can proceed to the next level without taking the bread. This way, you're rewarding the player to not waste effort on getting points (because it will be easier to sneak around) specially because you have to begin from the first level if you get caught. This, combined with the short loop music and the slippery movement makes it look like a rage-inducing game (which isn't necessarily bad, depending on what you were aiming). But overall it is beautiful and very polished. Nice job!
