Overall, it's a neat little retro game. The first impression the game gives is very curious as you get to watch the level being generated in plain sight, it's quite the show in its own right. However, at least once the level wasn't entirely ready when I began playing, so it still changed. Playing is very simple with the mouse and the game is rather easy, you don't necessarily need the stun feature to complete a level. It could be interesting to have the option to generate a more challenging level each time, with more litterbugs and such.
I'd very much like to invite your game to take part in our Game Development World Championship!
