Qix (Game Boy)
A port of Taito's Qix, the game where you build squares and avoid a giant spinny vector thing. Getting a high score rewards the player with the stereotypical Marios of the world.
A mummy-wrapped Mario and an Egyptian tileset, meaning that an Egyptian ending screen was planned.
A Native American Mario and tileset, meaning a Native American ending screen was planned too.
A hula dancer. There's no Polynesian Mario or tileset, so this is all that remains.
