Interesting concept, but I don't know if I really like the idea, or at least the execution of it. It's true that jam often corner us into making mechanic that might not be fun, but it's kind part of the challenge. Yes, it's original, but so is orange juice with cereal :) I'm saying this in the nicest way possible.
The art style and the music is really good though, so props to that. Coding wise, didn't run into any bug and control were good and clear, so in term of implementation of the concept, it's a perfect score.
So good job overall, nonetheless !
