Known as Gimmick! in Japan and Mr. Gimmick everywhere else, this 1992 release was an attempt by Sunsoft to push the graphical powers of the Nintendo Entertainment System further than they’d ever been pushed before (in order to compete with the Super Nintendo, which was relatively new on the market).
In order to do this, Sunsoft used all kinds of clever programming techniques using graphical tilesets and colours, and the end result is very striking. But it wasn’t enough to compete with the newer consoles of the time and Mr. Gimmick sank without a trace, into relative obscurity.
