So Awesome man! I loved it. I couldn't figure out what was going on at first but once I figured it out I had so much fun. I couldn't beat the hard ai with 100% resources. Really good job on the ai.
I do wish you could capture the neutral moons to bolster your production tho, because once you get get to 0.33 ships/second attacking the neutral moons is a waste of ships. unless you made them easier to kill, because right now it feels like the neutral ships are stronger than the player ships.
Anyway, keep it up. This could definitely be a mobile release. I would recommend a tutorial tho!
