I tried this demo (twice) and suffered from the same system lock-up bug. Basically, the game was fine until I drove the tank forwards. On the second time I ran the demo, I looked up and down a little and fired some practice shots before driving forwards, and having it freeze up. After half a second of moving forwards, it freezes up the game. I'm running on P4 2.26ghz, GF4ti4600, 1gb RAM, winXP pro, 1600x1200.
What feedback I can give... maybe have some better subtlety of vertical tank adjustment, perhaps move the turret in clicks or have a numerical gauge (bleh, I don't like the idea of a numerical gauge though, I prefer the simplicity of the look you have). Some means of knowing how far you've moved the turret would be cool though, that's why I thought clicks. You move it up, and it clicks audibly 5 times... you know that if it overshoots, you move it down so that it clicks 2 times, it would help refining shots.
Love the visuals ^_^
