Thanks and thank you for your idea, because I have thought about this, that you must move every unit on by one by just a one space and how to solve it. I was wondering if multiselect would work, but then the mechanic of getting together and then spitting to get to the tighter spaces would be gone. And I've already program pathfinding to enemies, so this would help so much and still keep the game same. Why I didn't think of it too.
SO THANK SO MUCH
