I just pushed a hotfix to fix the menu. I also added that UI arrow you requested, it slipped my mind the other day.
I read your other message and I'm glad she's having fun with it. I always intend for this game to be easy to learn and feel intuitive, so comparing your two experiences is very valuable. I'm curious how fatigue will affect your matches since it was intended to work somewhat under the hood to balance things subtly rather than work like a typical stamina bar system or something.
