Paint the Dead

You are an artist, and recently there was a zombie outbreak. You built your own gun with art supplies, and you have to shoot the zombies with paint to bring them down!
The gun's barrel is a brush, and it shoots paint. I didn't have time to finish it, so I just had to use placeholders for a few of the models. This will be edited to have fixes, and there won't be placeholders. WS to move up and down, R to reset if you reach the end of the map or die.
