Cheat Codes:

*There is a secret password zone in the "About" dialog box
*Hold the shift key and click on the black pixel of the 
 right eye on the image of Bug (in the "About" box). A 
 dialog box will appear.
*Click in the box, type BABYSEALS, and click either the WOW! 
 or YIKES! boxes (*not* the OK box)
*Now there is a new menu to the right of the Help menu. It 
 does not show anything, but when the blank area just to the 
 right of the Help menu is clicked, a new menu drops down 
 with the following on/off choices:

 Level Skip-
 Duck/Crouch pluc Up = skip forward one level
 Duck/Crouch plus Down = skip backward one level

 Flying Bug-
 Press Y to lift off and direction controls to move
 (Note: If this is checked, the Level Skip cheat also works)

 Invincibility-
 Enemies go right through Bug without hurting him

 Hitpoints-
 Bug react as though he's been hurt, but no hitpoints 
 taken off
