It is still very buggy, as you already stated. I tried 2 times and after I destroyed one the ships, the turn would not complete and neither of us could play. I could still move the controllers and click everywhere but my turn would not end. I tried everything.
It lacks audio.
Even with that, the battle is very engaging. I can totally see myself playing this game for hours while on the airplane seat without bothering other passengers.
The graphics are really good! Great effects! The clouds on the planet gave me the impression that I was moving. Did you make this all by yourself?
Anyway, please continue working on it. This game has a lot of potential! I hope to see future updates from you! Great job!
