I am enjoying the beta of Sandstorm! that is why I want to help make the gold version as good as it can be. I played for a few hours today and have found the first real issue with the game for me. When I move the mouse to lower right of screen it becomes disabled until I move move it back toward center screen and press the left button. This happened to me several times when enemies were to my right side and I had to pivot quickly. I remain in game when this happens but the mouse behaves as if it is out of the game until I move it toward center and pres the left button.
