Do you even gravity, Sonic? Arrow keys to move, Z to jump. Press Down while running to roll. Press Z while ducking do do a SpinDash. (You have to keep on pressing Z like in the old games) Have you found the jukebox? Should I use this Engine for SSSX? Tell me in the comments. If you say "Yes", suggest something I should add.
Remixed by Me (I only added the "Welcome to Test Level!" and redesigned the level.) Original Project: 360 Sonic Engine Test by MrLog, go check him out. Please note that this is a prototype, report any bugs and I will try to fix them ASAP.
