Yeah the different color hands has been suggested and first I though it might be a good idea. But now that I think about it I don't really know if it would help really, would your brain remember the color/side relation at all. I think I learned to tell the hands apart (even though I still fail at it quite ofter) looking at the guns, they do look different upside down. Of course that is a extra bit of mental processing you need to do though. Actually during development I even thought of the idea that left click would always shoot the gun that is more left on the x-axis and wise versa, but scrapped the idea thinking it would dumb it down too much.
Thanks for playing and the feedback! ❤️
