[Sonic Speed Fighters 2]

Will there be an option where we can custom characters?

[Sonic Fangame Multiplayer Controls]

So im working on an engine called the Classic Sonic Engine and im working on multiplayer(2-4 players max) but the problem is setting the controls because ive added a system that allows the players to choose their characters and they can have seperate and custom controls(usings options from main menu) but when i play it ALL the players have same controls. How can i fix this? Btw im using the Sonic Revival Engine 3.0 and i fixed the bugs in it also.
