This is a really really cool concept! One of the first I've played where being greedy can actually get you stuck, which is very fitting.
My main feedback is the fact that the levels have a lot of jumps that look like they could be done if my timing was just a little bit better, so I ended up trying the same wrong solution over and over before I realized the real one. But in 48hrs you managed to make some really pretty art and music on top of an awesome game, so bravo!
