Great concept and design. Unfortunately, as is usually the case with game jams, it really could have used a couple more hours of game testing. If you lose the spring, you're hosed and the game should reset. Also, infinite pit of falling. But I like the concept of multiple restarts that move progress forward. I kind of think that I should have been able to hop, but maybe that would make it too easy. Hope you finish this up and polish it a bit.
