EZ first place in the first 3 levels :). Fun idea. Best game i have played so far. Pretty cool that you have a leaderboard. One thing I noticed, is that the player gets stuck if he hits a platform horizontaly. I am guessing it's an issue with the physics material. Another thing you could improve is the player controller. Cayote time and jump buffering would be awesome. This would improve the feel of the player controller drastically. I have found a really great vid about player controllers. I would recommend that you check it out:
Overall the game is pretty fun and the idea is amazing.
