I've always liked these kinds of games, very well done, especially with the wrapping.
I'd recommend a colorblind mode, as with most other games where color matters.
The primary flaw in this game is that the AI is basically set in its ways and symmetrical. You spend the entire game defending against a perfect execution by the opposing team.
The second problem is the set ship routes. For one, they are way too restrictive and worse, once they reach their destination they just wait there like sitting ducks for the enemy to launch another ships at once.
It can be a really fun game with just a few tweaks here and there. For now, 2/5
A little too much randomness for my liking so far... But it's a great concept.
ps. A circle in euclidean space has infinite sides. A circle in spherical space may have one side.
This game really speaks to me for some reason. It's just so, beautiful. The music also is just amazing, is there a higher definition downloadable version of the background music?
