It's really hard (for me) to understand this game, but I don't think that just because I don't usually play those and thus have trouble understanding it that it's a problem for the game itself. It really isn't for neophytes, I guess. And that's alright. So I'll try to rate what I can.
The graphics are amazing and the only point I'm deducting on this category is because the text is hard to read with those colors.
The music is very satisfying too, even though it's a simple loop, it puts me in the right mood and I gotta love that BASS ! Very cool.
Other than that, I've tried maneuvering. It's pretty hard to get the hang of it and I still haven't managed to reach a planet yet, but the game being hard is exactly what it was made for, so it's a success, I think.
