Fun game, but maybe a bit too difficult. Playing on a flash game site I expect the levels to be easy enough that anyone can beat them. You might consider adding difficulty settings. As of this comment the levels can be INCREDIBLY frustrating, especially if you are trying to collect the orbs. It's fun, but if you're a less experienced player this could be terribly annoying. Just a thought.
Also, have you considered making the points you restart at after hitting an obstacle more frequent? I've gotten major progress only to hit an obstacle and restart a long way back in the level. Not exactly an appealing aspect of the game.
