Hey RavenStrike,
I'm so sorry I wasn't able to respond sooner. I really hope you was able to figure it out. To use a Gamepad and the Keyboard you have to: Connect the controller to the computer before opening the game, Join in with the Gamepad first then Keyboard. This way the keyboard joins as a second player. If you join with the Keyboard first the GamePad just controls the same player. I've added your username to the credits of the game. I'm just finiding and fixing bugs right now, for the Playstation release, new content, and DLC.
Thanks for your feedback, Sorry for the delay
Rafi
