There are some problems with the double-jump controls in this game. When I'm standing on a stable surface and jump twice, I occasionally do not get my second jump. This is not to do with running off of a surface and then jumping -- I am on the ground and jump...jump. The second jump has an unacceptably high chance of not working.
For those who didn't figure it out (XspraypaintX for example) the score is like golf -- lower is better. You need to get 3000 or lower for the hard badge.
Fun game, but the performance is terrible. I'm on a 2GHz dual-core box with a pretty decent video card, and the framerate was awful even with all settings turned down.
2/5 some of the larger enemies have very small weak points e.g. on the bottom of the craft -- but then the game will randomly place the enemy so that this weak point is off the bottom of the screen.
@zackman14: Flash games can indeed give you a virus if you're running a version of Flash Player with a code execution vulnerability. (Not saying that's what happened, but it is at least possible.)
