Reverse levels: Play level 1 and get to the very top platform. Get
above it by jumping and swing your hammer to see an outline of
a bubble. Keep hitting the bubble with your hammer until you
get a key. Use it to open a door that allows a password to be
entered. You must enter the password quickly. Use the hammer
to hit the jar to enter Spade, Diamond, Heart,
Club, Diamond, Heart, Spade, Club
as a password to advance to level 51. When that level is completed,
you will go to the previous level.
