Glitch: Frozen enemies:
When there are enemies on the screen, walk up against the wall above you. Wait until they are up against the wall as well, then jump. They will be stuck in place, and you can approach them and beat them down at your leisure. However, you will have to learn how close you can get to hit them without them hitting back. If you move downward they will become unfrozen and move again.
