This is certainly a neat little arcade experience on the DS, but as a whole doesn't work well as a full priced game. With very little story, a generic look, and an okay power up system, Nanostray does very little to really captivate audiences outside the genre that it roams. While most shmup fans will likely be able to enjoy this experience more as a fun arcade style shooter on the go, I think most will be disappointed with what this game has to offer.
