Vap's cheat for Wizkid locks your energy at 5, In one of the stages there's a lava flow of which you can only walk in if you have an even energy number, (IE, 4 or 2) The object that is hidden in the lava you need at the very end of the game, You can still do it, But it makes it much harder without said object.

I know. A minor quibble, But I thought you might like to know. :)
