Ultra Gorilla Sphere

As opposed to normal games where the player takes control of the character itself, Ultra Gorilla Sphere has the player move their character around by tilting the world itself (the exception of this being Ultra Gorilla Sphere Adventure). By tilting the board at various angles, players can control the speed and turning of the character. The goal of each level is to reach the goal gate before the timer runs out, and without falling off the floor. Bonus points and extra lives can be increased by collecting bananas on the stage. Early games use traditional controllers to play while many recent titles utilize modern technology, such as the accelerometers of the Wii and iPhone titles. The gameplay is similar to Atari Games' 1984 arcade video game Marble Madness.
