While working on missions for the non-demo game a few changes were made that would also improve the demo version. So here is the update to the demo.
Missile towers now have more fire range (still less vision), the explosions do more area damage. And the visual explosion now matches the damage radius.
The image quality of the terrains has been increased for all missions except the 3rd mission. Since the 3rd mission already used a better texture.
Also fixed a bug that caused enemies to counter attack from too long distances.
Currently working on 2 new missions for the non-demo release. These will both be placed before the 3rd mission of the demo to smooth out the difficulty curve.
