Looks neat and it plays pretty nice as well. Very impressive that there is an online leaderboard. For some reason the game is silent for me, but that could just be something with the engine not playing nice with my browser.
At first I mistakenly thought that the point of the game was to press shift to teleport between worlds, in order to get a higher score. It took an embarrasingly long time until I figured out that I was actually just restarting the game over and over, but as a consequence of that I did manage to see a lot of different levels, which was nice (:
