Cheats:

 These cheats will work in either the shareware or the registered
 versions of the game.  Key combinations have to be pressed at the
 same time.

 [E][L][M] - Gives you lids and slime.
 [P][A][M] - Level warp.  When you hit this combination, the game will
             freeze.  Press a number here, and you will be taken to
             that level.  You will not be able to see the number when
             you are typing it.
