Alright
quite a few bugs with the spinning wheels, and if you're quick enough you can "hop" out of a level by pressing the direction closest to the wall (even though you cant get back in). also, i didnt see a button to restart the level, just in case you do happen to go out. finally, i think the levels that weren't straight (you have to go in a diagonal line) were much harder than levels where one would just move straight.
otherwise, nice job, just fix up the bugs and it would be a pretty nice game.
