I'm glad that you love the art. Can you explain the difficulty with climing, did you climb with one hand or 2 did you put the gun back in the holster? Or is it with the controllers not having collision with the environment.
I have expeirence with making games but not yet in a Game Jam. I need a coder for UE4 I have the hardware to develop. Myself I will lead and will do the creative part.
