I'm mostly just confused which direction which is + and which is - in the x-axis by some reason. If it would take a load of extra work for only a little bit of convenience, it may not be worth it. On the other hand, it could also be convenient, just saying which square you're going to instead of obsessing over directions... Hahahaha... I don't have that much of an opinion on the matter. That's about that. Well... just assigning letters and numbers to the sides can't really be that much work... Maybe one could choose how one wants to do things...?
