Nice game, major bug though
I was enjoying this unil about level 4 when I went right through the wall on the right and couldn't reset. I know that bugs like these can be hard to avoid, but you should ALWAYS have some kind of reset button just in case.
Seeing as I didn't get very far I can't comment much on variety, but up the point i reached it was already starting to feel repetitive.
Still, good simple idea, nice physics, fantasitic graphics and easy to control. I like it a lot, I'd go 9/10 if it wasn't for that bug.
Ps, to the reviewer below me, there IS a music off button in the top right!
