Just watched a video of it on youtube.
One, wtf they're all girls, either the developers are loveist, it deals with the story somehow, or they're perverts.
Two, it looked pretty slow and boring, like gunbound but you don't aim or anything, you just keep attack-attack-attack-attack-attack move to next enemy repeat. I saw no combos or anything like that to spice it up, so I'm trying to understand what's so fun about it.
