Nicely done
Interesting game, reminds me of "Eclipse" (C64) and it's a bit like the first "Elite" games for the C64 and the Amiga, if I remember right. Since I am a huge fan of nostalgic games, I like this one here!
But if you could add some kind of gameplay, some goal to reach, and also an soundtrack, this would be even better, and I guess it would reach a score above 4. Nonetheless, very stylish, good work!
