I have said previously on this blog that no system is complete without a version of Hudson Soft‘s Bomberman, and the Megadrive has one in the form of Mega Bomberman.
Wiz ‘N’ Liz was developed by Raising Hell Software for the Amiga and Sega Megadrive only and was first published by Psygnosis in 1993. It is a side-scrolling collecting game with cute graphics and jolly music and can be played one or two-player.
Derek Brewster‘s Jasper is a decent platform game from the early days of the ZX Spectrum. It was published by Micromega in 1984.
Jasper himself is a yellow mouse, and his raison d’etre in life is: making it home across 22 screens of obstacles.
UPL and NEXOFT Corporation’s classic, cute Penguin Wars was initially released in arcades in 1985. This excellent Game Boy conversion came five years later, in 1990.
