Aww rats, sorry to hear that. It should be on one of the settings buttons or accessible with F1 regardless of your input method
That's what I did. I used F1 to open the options, and tried both setups. With the keyboard setup, nothing on the controller worked. With the controller setup, that's when I had the problem of only jump working. I also forgot to mention that O was my jump button, when it should be X. Very unplayable on my ps4 controllers.
Yeah the system could be more clear. By selecting one of the ability buttons the game will start listening for inputs. From there, you can press any button or trigger to bind that action to it. One bug is that if a button is bound and you bind a stick or trigger, it will also keep the button binding. You can get around that by also binding an unused button.
