Take the protagonist, with related verbs, of every major 80s hit, along with the enemies, the art assets, and the midi signature. Put them on separate, concentric roulettes, and spin. Spin every few seconds. Try to win.
You'll find yourself meta-gaming, you know that as the Defender jet, you can merc those rainbow cascade things pretty well, but in the process of getting over there, there is a good chance they'll turn into goombas, and you'll get hit. Or maybe you'll hesitate, as Link, to walk up that hallway, because you could become the Space Invaders turret, unable to move vertically, and get caught by pursuing Gauntlet ghosts. It's clever, because this is no mere mash, but a full blooded remix, where added depth emerges from the recombinations.
