Happy to hear you enjoy the build :)
great tip for the ledge controls! i think having an input of direction pull you up would work well
the reason for the aim being off is that bullets drop, so often that has to be taken into account on the aiming, the only option for this is moving and lowering the aim retical for each gun depending on there range and drop off, which may come in a future update :) depending on where i go with combat and weaponry
