Undead Defense [Version 1.4.7] FIXED

----FIXED ^_^----DON'T SHOOT BACKWARDS! Go to my music downloader, 2nd page. This game is simple to beat, just kill kill, upgrade upgrade. Can't shoot backwards, because can you do that in real life? Na, I didn't think so either. Easier with more people, obviously, and the bosses are neigh impossible alone.
