I see, thanks! My ambition is to make a horror game completely free of ui, so I'm experimenting with different options and your feedback on the missing cursor really helps, it means the outline is not enough.
I think there may be some visual trickery about this like locking the game to the 1.85 : 1 aspect ratio or something diagetic like a literal arm and hand from the corner of the screen. There may be a GDC talk exactly about how to do "UI-less" games
