Dunno if anyone else here ever played or heard of it, but I used to have
Zoom! for the Genesis...it was kind of like an evolved version of Q*Bert in that it had a variety of enemies, and you raced around on these oddly shaped mazes with all these little tiles, and you had to race around and claim all the tiles on a board to advance to the next, and there were also a bunch of power-ups and the like.
