After so many months of searching, I finally came across this game at the resale store in town today, and HOLY CRAP IT WAS WORTH IT. I'm certainly not the first on the site to rave about it, nor will I probably be the last, but this is one immensely kick-ass shooting game. The theme is unique and silly, the monsters look great, and the difficulties will really kick you in the teeth if you think you're so hot at bullet hells.

Verdict: F*cking Excellent. I don't quite remember who last raved about it and called it the best sh'mup ever, but that's an accolade that might not be totally undeserved. (I have certain reservations about such an extreme statement, as I've still not tried the other CAVE games on 360, any of the Raiden series, or Akai Katana, all of which I've heard are also fantastic).
