Kid Chameleon (Genesis) (gamerip) (1992)

Sega-Genesis's rival to Mario lol. The music fit just right for each of the earlier levels that were introduced. Brutally difficult as the game progresses but the tunes keep you motivated to keep getting farther. Even the options screen song rocks! Epic soundtrack for an epic game.
Everyone likes to throw shade on GEMS, it seems, but it can make some banger tunes if you know what you're doing. This game proves that.
Games like Toy Story, Comix Zone, and Vectorman used GEMS pretty well. It's just that many developers had a hard time using it to it's full potential due to not being used to composing for Genesis hardware or were just straight up incompetent at utilizing GEMS well.
