It is what it is. It's a schmup where you can move around freely (except for when it puts you on rails and you just move the camera to dodge obstacles) and shoot things with your normal attack or special attack. It has dreadful voice acting and a story that I couldn't possibly care about, and it adds nothing to the genre, but it's still not a terrible game: just average. If you need something to play and like the genre, it'll give you a little enjoyment I'm sure.
