First of all: Great game, keep up your awesome work! I didn't have time to read the whole thread, so forgive me if someone mentioned this before: I have this problem that the sky is somehow stuck to my view direction. If I move my mouse, the sky moves, too. For example, when I look only slightly upwards, the sky texture doesn't cover the whole sky: the center (?) of the sky texture is stuck to my view direction, so most of the sky is behind the buildings. When I look more upwards, the sky moves with it. Pictures: 1 2 3 BTW you should integrate openal in the menu - sound is much better with it and good sound is important in games like this.
