Hey yeah i found the sensitivity slider after reading your answer and I still find it too high. Also yeah the settings menu is hard to find because of the button's color.
Not only that but when I minimize the window and open it again the mouse is gone meaning I can't access the settings anymore.
You might wanna use the Application.focusChanged delegate to detect changes in the focus and do Cursor.visible = true and Cursor.lockMode = None or just spam it in the fixedupdate :D
