Unlock ther hidden Grave Yard Level
First go to the Cathedral (level 6)ŕ and flip the end switch. Don't 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 wasn't there before. Go in there 
and kill the enemies and flip the switch to open another door down there. Then 
hopefully you'll go on the right "end" teleport. You'll beat the level then 
will be sentŕ to the secret Grave Yard level.
