Mick & Mack was a McDonald's licensed game developed by David Perry at Virgin Games. It appeared on various Sega systems and the Amiga, though they cancelled the SNES version. It is a platform shooter game with an environmental theme. The game was shown at the Winter 1993 CES, apparently after the Genesis version was already out. If I were to venture a guess, it was not completed because it would have come out too long after the Genesis version, and possibly too close to the release of Cool Spot. The in-game copyright screen says 1993, so it was almost certainly in development after the Genesis version was already release.
