An excellent 3D rail shooter/shmup. Genre-defying in gameplay, with a plot of pure anime sci-fi nonsense. Without reading elsewhere, the central conflict would be incomprehensible. But who needs plot when there's so many creative encounters and bosses, so much level variety, and a solid difficulty curve? I have a few criticisms involving some of the controls and the initial opacity of some bosses. They're all comprehensible after a few attempts, though. This one lives up to its reputation.
