The art in this is amazing! The gameplay reminds me a little of N+. I really like the idea of defeating your clone. I think the wall jump and the slipperiness could use a rework, the player was very hard to control. I think the time limit could probably be increased as well or it could be the same for your run and the clone's run. Having one time for both seems way too fast and with the movement not being very tight it feels like you cannot get any practice with a level before losing in it.
