Mega Mash starts innocently enough. You have just bought a game compilation cartridge and put it in your console to play it. It doesn’t work however and, frustrated, you break the cartridge. Then you give it another go, why not? That’s when things get weird. Mega Mash is compilation of 7 games gone very wrong. As you play you will frequently skip from one game to the other. Things you do in one game will also effect the other games. Can you successfully navigate through multiple game worlds to beat each level?
