When the title screen appears (where Zool is hauling himself up on the Z and the L), type
goldfish
and the screen should flash once.
On playing the game, the following keys are operative:
1 - Zool becomes invincible (you must press this again if you collect anything which makes him temporarily invincible under normal circumstances, and every time you start a level)
2 - Jump 0.1 level (i.e from 1.1 to 1.2, etc)
3 - Jump 1 level (I think I have 2 and 3 the right way round...)
4 - Kill Zool
These are, of course, on the UK version, but with any luck they should work on any version.
