I know it's an early demo, but already it has a very nice visual style and art direction! I like the simple drag control scheme (my game uses the same interaction in touch mode hehe). I also really enjoy the way friendly and enemy units engage with each other, good job.
a few things to note:
- small stuttering at times from certain actions eg. firing, camera zoom, revealing areas (could be gameobject instantiation related?)
- UI text could be a bit bigger in general
- loading screen to smooth out transitions between scenes
- the dithering is a bit too much especially on effects like smoke etc
- in game dialogue UI could use mouse controls eg. LMB to go to next line
- camera controls could use more options (MMB drag pan, screen edge pan)
