Upcoming redesigns for several Alterworld Badniks are in the works at the moment.

Shadow the Hedgehog is coming with his USP Tactical and looks from AsuharaMoon's Another Shadow in Sonic 1 and Double Jump from Sonic Megamix, though suggestions are encouraged.

Here's gameplay footage showing the recently added Shadow, Tails Doll (who serves as an optional hard mode, chasing you at the same time as Sonic.EXE) and some of the original level design for Redux Mode. The speed of X and TD are still subject to change.

There have been a lot of complaints about OSF's difficulty; this will be addressed in the next release. There will be more ways to evade Sonic.EXE, and a remixed set of levels designed with the new mechanics in mind. Stay tuned.
