1. Add a option to the ESC menu list called Mobile Mode

2. When Mobile mode is active an left and right arrow is placed in the cornor of your screen so when you click it with your cursor it rotates your character (so it becomes interactive with your touch screen

Edit: you could add 2 screen buttons one attacks and the other uses an item so hawk eye and combat would be easier for combat. (For making mobile mode easier same as the arrows their touch screen interactive.)
