I have mixed feelings about this game.
As for the graphics: they're beautiful. The animation is smooth and the character design is great. I never get tired of saying of how great they are for a game that's worth a few bucks. And while it depends on your personal music taste, the music is great to listen to as well.
I was really dissapointed to find out how short the game was. I managed to beat story mode in 30 minutes! Not only that, but I find the gameplay very repetitive. It's always the same map, and the same enemies. The setting changes a little as the gameplay goes on, but the only thing that changes is the color and difficulty of the same enemies over and over again.
I also find it frustrating how the game doesn't expand to fullscreen, unless it's just happening to me. My mouse often goes off-screen and I end up moving the window and having to re-adjust the whole game window.
Overall, the game is fun for a few hours then it just gets old unless you enjoy playing repetitive games. I hear that there are more features coming in the future- I'm interested in checking them out.
