Interesting game, but with one major flaw: it gets laggy after a while to the point when even clicking on in-game buttons is taking effect after a massive delay. I even had to collapse the game to write this review, because the tab with the game temporarily stopped responding.
PS
It looks better now. One suggestion: add a "restart" button below the "home" one after you lose; one bug: when my character hit the shroom with coins and rotated himself he stayed flipped.
Oh, obviously the scoreboard is not working.
