Amazing game and amazing ambience.
luv the gore xD
but is it normal that the mouse just gradually goes up by itself?
Hi, that's not normal. The game works by locking your real mouse to the center of the window (to stop clicking outside the window and losing focus) and it checks for any attempts to move it up or down and applies them to the game-cursor. If it keeps drifting then you might have a mouse problem, a driver problem, or some weird conflict I didn't account for.
