Space is bound to jump again, exactly as before: same action name, same physical_keycode 32, same jump_velocity -190 and gravity 980, so the measured jump height is 20.07 px, identical to the reading taken before the binding was removed. Single jump only, no double jump. The debug flight goes back to Space for up and S for down like it used to, with the arrow keys kept as an extra. No gameplay content touched.
