The game currently only supports up to 1920x1080. It is something we may increase down the road. And the window mode of the game is more or less, full screen borderless mode. If there is anything else I can do for you please let me know. Thank you.
If I always appear prepared, it is because before entering on an undertaking, I have meditated for long and foreseen what may occur.
