Secret Grave Yard level
Go to the Cathedral (level 6) and flip the end switch. Do not complete the level. Instead, go back up the green key stairs and turn right. Go down the hall until you see an opening in the wall that was not there before. Enter it, kill the enemies, flip the switch to open another door down there. Go on the right "end" teleport to complete the level and travel to the Grave Yard.

Glitch: Health boost
If you are at low health (1-10), there is an easy way to to boost your health by about 30. The lower the health, the better. Pull out the Phoenix Rod and walk next to a wall. Blast the wall, and if you are at low enough health and did the trick correctly, your health will go up.
