All this is is a glorified level editor, with no levels. Sure, there are a few tutorial levels that were in the first one, but as far as I can tell, you haven't put and new content in in that respect.
I give you an 8/10 because LEVEL 20 IS NOT HUMANLY POSSIBLE. Also, it gets repetetive and is kind of annoying. But nice physics, did you use a physics engine?
