Wow, the first thing that stands out in this game is absolutely the art. Incredible. I really loved the detailed running animations and the neat designs of the powerups. The game was a bit too long and repetitive maybe, but other than that I had a great time! Would have loved an option to shoot backwards instead of having to run forward and turn back, but that might have altered your initial vision of the game so no need to pay attention if you don't agree :)
