In the game you take on the role of a scythe-swinging nun who is out to rid the world of zombies. But you also get some other weapons along the way. However, the game is so basic that you can, and I did through several levels, only tap the attack button. Since you're swinging a scythe it propels you forward and you can do an entire level that way. You can also do an entire level by simply bunny hopping through it and taking little to no damage.
