using the controls listed, i can't get the character to jump or climb for the life of me. I have tried on every surface in the environment that looks grapple-able and it only works like a fifteenth of the time. Really klunky.
I couldn't get the jump to work at all until I accidentally figured it out. The instructions here don't explain it very well. To jump, hold the left mouse button, then drag the mouse (while holding the button) to determine direction and distance, then let go of the button to jump.
