Hi!
The map is really awesome!
Congratulations!
Here is some suggestions to the map improvement:
-More armor/weapon/space speed levels, I think 10 levels isn't just enough
-Maybe more type of ships, for example an ultimate ship that can destroy planets, because after some time playing we acumulate a great amount of money that we can't use
-If you know how, you could do a AI system for this map, because sometimes, due to internet problems or other reasons, people would like to play in singleplayer, this is just my opinion
-to turn the game more realistic, doing something like make a group of planets, move in circles around a unique star, should be cool I think, but maybe that should give a lot of work since the planets are buildings.
And I have a doubt: for what the stars are needed? I thought it was to destroy ships when they pass near the star, but that doesn't happen.
