Same as Crazynoodle! I got it today, and it's one heck of a challenge. It took me probably 10 tries to get through one of the first few levels. I guess I'm not much of a physics buff, eh?

As for Objection_Blaster's comment, believe me, I'm probably worse than you at this, since the one level I had to skip was "Impale Sticky", and that's, what, the fourth level? I blame Thanksgiving break for making me stupid. _
