I think this is a really addictive game for a few reasons. For one, I think the art is pretty freaking cool. The concept of a high-tech alien shooting up a sweet fantasyland makes me smile. There are a few problems I see with the game though. When you come into contact with the blue or brown bags that are explosive, they don't seem to hurt the things you are trying to kill. That's annoying. Furthermore, there were a couple of times where I was excited to get to the next level and in doing so didn't pick up the ammo I needed. During those times, I was really wishing there was a store button that I could click on and get ammo. One other thing that I think would be cool would be to show the weapons actually changing as some other users have stated, but that wasn't that big of a deal. I am waiting for a sequel!
