Nanostray 2 hands-on at Kotaku.

"While Nanostray was a solid side-scrolling shooter for the Nintendo DS, it wasn't without its fair share of problems, the most glaring of which was the endless continues, that made the game far less of a challenge than it could of been. Along with requiring the touch screen for weapon selections, these two features bogged down what could have otherwise been the perfect little handheld shmup. Now Nanostray 2 is still a couple of months away, but from my time with the preview build of the game Majesco was kind enough to send my way I can say that it triumphs over the original in every way."
