Help Wanted! For The Endless War, I had came up with a way to make a party-thing, where the characters all follow you, just like Earthbound. I was wondering if anybody could improve it. Earthbound uses a thing where it like... repeats the leader of the group's steps. Please help me improve this!

You could make an array that saves the player's last moves. So 0 would be stay, 1 up 2 right 3 down 4 left?
