Wow!
Amazing game! Nothings bad, but I do have a few suggestions:
1. A way to organize my fleet. I love the enemy fleet randomization, but it would be nice to set it up myself. Maybe even buying the ships and setting up a formation would be cool!
2. A music selection system. And get more than one track, too.
3. During the three-sided battles, the force up top always gets to the battle last, letting the other ships kill each other for a few seconds; reposition the ships to fix that.
4. Being a Testudon would be AWESOME.
5. If I can't be a Testudon, keep the game from showing one to me when I die.
6. Finally, a saving system. Even codes would be great; it's annoying as hell to have to start from THE VERY BEGINNING.
Great game, good job.
