VIQ-Bert
VIQ-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. Unlike the original Q*Bert enemies, they don’t
change back the color of the game tiles, but contact is deadly. Another way to
die is to fall off the pyramid. Later levels require coloring the same squares
multiple times, and even later, you cannot pass the same square twice without
changing the color back, so a strategy element is introduced.
