My best so far

Pyweek 13 is over! The rankings page doesn't seem to be working right at the moment but I can see that we got
 
Fun: 3.4
Production: 3.3
Innovation: 3.5
I'm pretty happy with this :)

From reading the comments it looks like there are still some glitches, but people generally liked the level design ^_^

I think I may do some more work on this game and attempt to fix some the bugs. I really need to learn how to do collision detection properly!
