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.

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.
