Skyworld

Skyworld is an unused stage in Super Smash Flash 2 based on the stage with the same name in Super Smash Bros. Brawl. It could be found in v0.9b's files, alongside Lake of Rage, Butter Building and Ice Climbers. Skyworld is much more finished than the other leaked stages, and even has a DAT of its own in v0.9b. However, it may or may not be a future addition in the game.

Layout
Three platforms make the infrastructure of the stage along with a lower platform that can be used to aid a recovery. Palutena's Castle is in the background. In the Brawl version, the platforms would break, if they sustained enough damage. It is currently unknown if the platforms will break in Super Smash Flash 2.

Trivia

 * As seen above, in v0.8a of the demo, a glitch will sometimes cause an inactive thumbnail representing Skyworld to appear on the stage selection screen which hinted at this stage's possible inclusion in a future build of the game.
 * Skyworld is listed as DAT26 within version 0.9b's game files and contains "Title (Kid Icarus)" from Brawl as its music, but goes unused. It was reused only on Palutena's Shrine stage in Beta. In Beta 1.1, the track is now unused, as it was replaced with a remix track.
