Realistic, minor improvements would make so much better Nice realisitic clouds and perforrmance isn't bad especially considering how hard 3d clouds are. Unfortunately the bright white makes subpixels fairly obvious. Think adding proper look-based flight controls and flying above/below clouds (bonus points for some basic speed physics), a simple distant sea or ground texture in the skybox and time of day support would make this really relaxing. Sound effect also poor quality.
