Every other combination of keys works when traveling in the game, except for:
<^ to move diagonally up left. I can do it in reverse but not forward. My keyboard is fine as far as I can tell. No buttons are stuck. Aside from it being unusually squeaky, everything about my keyboard seems fine. So I'm gonna guess it's the games controls?
I can walk up and I can walk left but I cant walk up-left.
Nevermind!! My computer must have just been confused. After I switched away from the game then switched back, all the keys started functioning.
