Although I feel this has a lot of potential, the incredibly rough state of the game at present makes it a bit hard to play. As well, level 3 can be fairly easily cheesed using clever maneuvering to bounce yourself against the vertical edge of a wall while the other guy bounces up and down on spikes - though admittedly, that could be the correct option and I haven't realized it yet.
tl;dr - this feels more like a tech demo than a game, but I would be interested in seeing this concept worked upon.
