However, due to its rampant difficulty scale and lack of credits, it may not be for amateurs or non-shooter fans.
Nanostray 2's stages shift between horizontal and vertical, changing up the perspective nicely. Either way you go, you'll shoot lots of enemies before battling with a nearly indestructible boss, chipping away at its weak point with a number of power-ups. It's old school at its best, although it may be too much for its own good. The game works on a progressive "do it all in one shot" system with few lives and credits. Run out of both and you'll have to start all the way at the beginning."
