I don't want to poo-poo anyone's good time, but I find this game to be absolutely f*cking atrocious. Boring as hell and virtually no redeeming qualities. Sadly, not even boobies could save it from being a less-than-pedestrian, lazy, and flat-out boring shmup. It looks like a hi-res N64 game (only slightly exaggerating), and plays like the developers got bored after the first level.
There's one level toward the end that's slightly interesting because it reminded me of level one of Gate of Thunder, but that's followed up by a boss rush over a plain black background.
I really wanted to love this game, and hoped all the negative comments I'd read about it on Shmups.com and other places were unfounded. Alas...I feel like I was robbed out of $50 for a game that would have been overpriced as a $10 XBLA game.
If you want a horizontal shmup on XBLA or Games On Demand with a dash of titties, you'd be much better served with Deathsmiles or Trouble Witches Neo.
Sorry to drop a deuce on your thread. The "art book" is nice, though!
