Nice, idea, I found myself taking the upgrades that make your gun much more annoying just to see how things would develop, it was kind of fun destroying everything though you shouldnt. However there were many broken collisions where I just couldnt move which quickly made me frustrated and so I had to stop playing. I like that you made an intro to the game. I wasnt the biggest fan of the art, but the music was cool enough, though a bit repetitive.
