up on japanese psn and 3ds (if you have a japanese 3ds)
It's pretty fun. It's like Kid Icarus 3DS ground sections, with finicky lock-on instead of free aim. You even have that move where if you dash to evade an attack before it hits, you let off a more powerful counter-shot. I don't know the history behind the game but it seems tuned for 3DS/handheld play. There's a completion time ranking and all three missions had par times between 5 and 10 minutes.
PS3 port is sloppy (unless the 3ds version runs like peace walker psp bad). Usually you expect 1080p and 60fps on these things. This is maybe 720p (at least not 1080p) and has frame rate problems. One of the levels runs at ~20 fps throughout. There's not much going on with the game so I don't know what's up.
(it's also crazy animu. random j-pop music, exaggerated bouncing breasts, guys with pink hair, and tons of cutscenes about friendship to skip.)
