I see a bunch of comments about the badge not working. Does that mean even after completing the game nothing registers of just the tracking of getting to level 9? I think each area counts as a level since there seems to be no leveling up of your character.
A game like this really needs to detect when the mouse is no longer over it. I can't count the number of times I click off the edge of the game then I can no longer move and I get hit. It's still fun just aggravating!
