This is an engine for the spindash mechanism for Mr. Orange 3 (moved on). Hold down the down arrow or the S key, then press the direction you want to go (A <- or D ->). This isn't perfect, but it should work as a way to speed dash in the game and also attack enemies that come!
I belive i did this all myself. Feel free to use this all you want. I made it, did not finish, and moved on to other orange-related projects. This engine can work on any round character and sonic characters.
