Pete may encounter some items along the way to help him:
Extra lives will increase Pete's chances of success.
Bombs will help Pete subdue enemies. Place bombs using "b." If you press "b" while Pete is running, Pete will throw a bomb in the direction he is facing.
Pete's cane will help him with some obstacles and enemies.
Should Pete come across some unholy creatures during his travels, a crucifix should be most helpful in keeping such unspeakable things at bay.
