Kirby Tilt 'n' Tumble 2
Kirby Tilt 'n' Tumble 2 was an unreleased Kirby game and a planned sequel to Kirby Tilt 'n' Tumble, and it would have have been played on the Nintendo GameCube and Game Boy Advance at the same time. This was made possible by using the Game Boy Advance as a game controller via the link cable. As its name suggests, Kirby Tilt 'n' Tumble 2 was planned to feature the tilt controls that appeared in its predecessor.
Kirby Tilt 'n' Tumble 2 was originally scheduled for a May 2002 release, but the Kirby theme was eventually scrapped. Kirby Tilt 'n' Tumble 2 was reintroduced as a game starring an ordinary marble, titled Roll-O-Rama; this version was shown at E3 2002 but was ultimately cancelled itself.
An early version of the game was demonstrated at Spaceworld 2001 by Shigeru Miyamoto. Kirby Tilt 'n' Tumble 2 would have retained a majority of its predecessor's style and gameplay. However, the largest difference was that the player would control Kirby in 3-D rendered environments. Similar to the first game, the player could have moved Kirby around by tilting the Game Boy Advance, which was made possible by inserting a tilt sensor game cartridge into the device.
Kirby Tilt 'n' Tumble 2 was jointly played via the GameCube (on the television screen) and the Game Boy Advance. A shift between devices would occur if Kirby fell off a ledge during gameplay from the GameCube, which caused him to directly transition down to the Game Boy Advance screen. According to Miyamoto, Kirby Tilt 'n' Tumble 2 would have featured the ability for the player to write "programs" (such as mini-games) onto the Game Boy Advance tilt cartridge.
