um, small glitch. If you walk on to a curve going up, and jump right as you start to turn, you will jump into the ceiling and get stuck. this might also help going other directions a s well. Game is still awesome though, 5/5.
this game is educational because it instructs you on how to use a bazooka with infinite ammo to kill zombies most efficiently. This game alone has made me more prepared for the zombie apocalypse.
