The game doesn't lock your mouse, and xbox 360 controllers (the type the game supports) aren't exactly common now a days. Because it doesn't lock your mouse, you constantly click things on your other monitor while trying to play in game, making it virtually unplayable. You have to constantly move your mouse the opposite way of your second screen to make sure you aren't clicking out of the game. This makes it so instead of looking left, you have to turn and look right so far that you end up facing left
