Shantae Advance (cancelled Game Boy Advance game; 2003)
Shantae Advance, also known by its in-game title Shantae 2: Risky Revolution, was supposed to be the sequel to the critically-acclaimed but commercially unsuccessful 2002 Game Boy Color game Shantae. It was developed at WayForward technologies by Shantae creator Matt Bozon on his own time. The game would feature improved graphics from the original, as well as other new features, such as the ability to fly around Sequin Land on Sky's bird Wrench, who has grown to an enormous size. Shantae could move between the foreground and background scenery. There was also a 4-player Battle Mode, where players control miniature versions of Shantae, Risky Boots, Bolo, and Rottytops. The plot apparently involved Risky Boots using a "Tremor Engine" to wipe out Sequin Land. Shantae could later use the Tremor Engine to alter background scenery and gain access to new areas. The Monkey and Harpy transformations would have returned, and Shantae would have the ability to swim. Some screenshots also showed Shantae wearing blue pants instead of red, suggesting the ability to change costumes. A playable demo was created which showcased the new features and gameplay. A Plug n Play TV game version, titled Shantae TV, was also planned.
Unfortunately, since the first game did not generate much income, WayForward had a difficult time finding a publisher, so the game was cancelled. Several features, such as the foreground-background interaction, were implemented into Shantae's eventual sequel, Shantae: Risky's Revenge, released as Nintendo DSiWare in 2010, and later ported to several other platforms. The demo was subject to a playthrough stream on Twitch.tv by Matt Bozon October 3, 2014, confirming the demo still exists. Matt Bozon has stated before that he would like to release it to the public somehow, but this has not yet occurred.
