Will there ever be an option to change the control on the keyboard for each individual player
I have controllers that i want to use on my computer, but they won't register as a joystick. They can however be programmed to push keyboard keys. But now the problem is no matter which players keyboard configuration i do it will always change the others.

zep if you could add individual keyboard customization that would be great.

I have an idea for a workaround:

Use the Keyboard+Mouse option but forgo the mouse and only use the second set of keys you have planned. It can only work for two-player games (like the 2P Arena), but at least that's semi-individual keybinding!

this is what i am currently using but there is a problem. The player that is using just the keyboard has a slight unfair advantage only being able to shoot in 8 directions. (I have fixed this problem though setting quantinization to 8 for Keyboard+Mouse to 8) It is still unfair because the player with keys+mouse can shoot any direction just by standing still. The player with just the keyboard can only shoot towards the moving position.

Also i want to create a 4 player game.

The keyboard player isn't able to JUST shoot where he is moving; using a dual-stick control method (Default WASD+IJKL) the keyboard player is able to shoot in 8 directions while standing still as well. What I am somewhat afraid of is the fact that the keyboard player can also shoot in 8 directions while moving a different direction as well, and I am not sure the keyboard+mouse player is able to do that...

As for the other two players... Hopefully you can get a joystick that actually works like a joystick.
