It's not totally my kind of game but I'm glad I bought it just to show support because it is a really great game.
Not really for people that just like to point and shoot enemies in games, you really have to do some thinking in this one.
Kinda reminds me a bit of Space ace in the arcade:

as you have to learn in what order to do certain moves, although it's far deeper, more involving and more difficult than Space Ace.
