I liked the game much, but a few suggestions: Play some music. make the AI work better maybe (sometimes a few attacked but the base was totally full of enemys)
but its good that they use upgrades.
I found some bugs:
The attack upgrade of the 'evil' side works but it doesnt show the lvl in that little square at the weapon type, it stays 0.
The armor upgrade was messed. 1 player had 3 upgrades but 0 armor, another player had 3 upgrades and 6 armor. another1 had 4 upgradees and 4 armor. (all on the evil side, I think it went good on the good side (the rosilia)
And I think the ship has a little 2 much hp. dmg is good
