Notes for this version: According to the developer, the game still requires optimization but there's now a bit of AI in it, although all it does is defend instead of attack. This version of Celestial Cunning has five available units. Most of the available commands work as well.
Celestial Cunning is an ambitious homebrew RTS game with a sci-fi flavor. You can see from the screenshot here that it's still in its early stages, but it does look quite promising.
