While this game is interesting and fun, it is somewhat hard to get the hang of. Do not attempt to use just a keyboard and mouse to play this; the best option would be a 360 wireless controller. Even with that you may still be left with playing with the controls. Including the game has a horrible time remembering you choose to not use inverted controls...
The music is decent, however I felt it was not very fitting of the game play, this is also one of the problems I have with it. While the music isn't the focus of game play they could have done so much better with which scores they choose for one. Good example of this would be the temps from eve online. Of course eve onlines music becomes pland after a while, however it takes a rather long time. Within the first 30 minutes of playing this I switched to custom music. (I also own the OST of this)
The spikes of how hard this becomes go from, not hard at all, to extremely hard. While that is alright at times, the active save points are horrible and you will be replaying 'segments' over and over again since some things tend to vary.
If you are into this kind of thing, or like 'Gundam'-like space play, this may be for you.
