Took me a few hours to make, But feel free to improve on it, Just please give me credit and do not recolor it or add stories without changing scripts. Also be sure to check out my other games: Tower defense, Shoot 'em down, and Scratch cat attack! (this is my worst one.) As in all my projects some credit to a book I read called SCRATCH 2.0 GAME DEVELOPMENT HOTSHOT, I highly recommend it. The song is "black vortex"
