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.

Metal Sonic is coming with his moveset from Metal Sonic Hyperdrive. Credit to Darkon360 for the sprites.

Some changes being made to Marble Zone's alterworld graphics

My main goal for OSF's development right now is improving the physics. I'm aiming for the next release to have 1:1 accuracy to the original game in terms of controls. The collision system has been majorly reworked to this end.

There have been multiple requests for an Android version of OSF, so I'll bundle an Android version with the next release, although I can't promise that it'll be particularly polished when compared to the main PC version.
