Really fun but really easy to get stuck in a wall or ceiling on certain level. Just refreshing the game gets be back to the beginning of the room, but it's irritating to have to do that so often in some particular areas.
I don't know if it's just me, but sometimes the game will "blink" for lack of a better term, and I'll get the distance scored, but not the cash I collected for the round. This has happened to me three times now, on two different browsers.
