The idea is really great! I love the fact that you're your own enemy, literally. It's kind of disappointing that the movement is not that fun, sometimes you build up too much speed and sometimes you don't get any without reason, walljumping needs very percise inputs to be able to get any speed or to jump from the wall at all. Also the trails sometimes seem to spawn somewhat randomly, very commonly killing you where you stand. While the execution isn't that great, I really love the idea and i think the art is pretty good.
