your comments are on point, and make a lot of sense.
as we have no UI specialist among us, do you have any suggestions? In the current UI we tried to hide elements as hard as possible not to clutter it
I'm no expert myself, but I would recommend against putting any buttons in the corners/edges of the screen. I always give it some padding. I find its hard to see buttons placed right in the corner, especially if they are small as the ones you have in the game. My brain kind of just ignores it, assuming that it is some kind of HUD.
