Juz a suggestion: The virtual look on-screen pad from the game should be removed to provide more window space for the game window itself. The control scheme should also add an auto-firing mode that when d stylus glides over an enemy, it automatically fires and stops when itz not over an enemy (or any target for that matter). Note: try the Diesel Engine FPS tech demo to know what I mean.
Hope Mr. East could think more 3D games to port for the pocket PC!
