VIQ-Bert

IQ-Bert is perhaps not the first, or even the best variation on Q*Bert for the VIC-20, but it is by far the smallest, weighing in at under a single kilobyte (programmed for the 2002 edition of the MiniGame Compo coding contest). As in the original Q*Bert, the player moves on a 3D pyramid, coloring the fields of the pyramid as he/she/it moves. Coloring all tiles clears the level. This would be easy were it not for the enemies moving around in haphazard patterns on the same pyramid.
