The base drum sound whenever you hit a wall was great and totally fit with the music and the visuals of the game. Generally you found a very coherent atmosphere for this game. The game mechanic was a bit strange I think, holding the mouse-button and just shortly releasing it with as much speed as possible and hopping through the level in straight lines was actually the only strategy that got me somewhere, and then you kinda loose the physics part of the game, where you have to think about trajectories. Not sure if it was intended that way though.
All in all a really nice and atmospheric entry. Props!
