I first played through on the easiest setting just to get a feel for the controls, and I scored 494,100...  though I don't really count that, especially since you don't even see any titties!
Then I beat the game on the hardest setting, with 1 continue, and scored 518,400.  I got trapped in the corner by Medusa, and spamming Nina's F F F didn't work.  Game is kinda broken, in that you can get trapped in an infinite loop by the computer, which you cannot jump out of or block.  I then switched to Martha, and spammed her D D in the air move, and couldn't be stopped.  I guess the game is pretty broken, because I beat it easily on the hardest setting in my first attempt.
I did love the consecutive loop of girls at the end, creepy wink after creepy wink.  The Native American chick would've had me fapping, if she was a real chick.  I will probably pull this game out once or twice when I have friends over for a quick laugh, but it is so unbalanced, it can't really be played seriously.  Too bad you can't post the ending on youtube, it is pretty hilarious.
