I tryed the game seemed fun so far but I kept getting bothered by one thing. I was running game in window 640x480. My mouse hand showed up over the game so I got confused between using mouse hand verses the cross hair to aim and shoot. I also had problem where i had to move my hand off the window to move the crosshair over target but then when i left click mouse to fire the gun the whole game was no longer the focus and I activated another program running in another window in the background.
