looks kinda cool... that is looking by the trailer at least, i will give it a shot
edit: i played it and for the early state that it is its not bad at all, the demo was uploaded 3 months ago and it says combat prototype 0 so i assume its the first ever build and so for an early state of a project its not bad and although it does have quite some bugs its still good... like its not that polished or anything but it does have quite the amount of moves and abilites so that's really good
as someone who loves Hack & Slash games and also developing my own Hack & Slash game, i think this has potential and if you want this to be a fully fledged game (which so far with how the game is focused on magical girls and actually has a story it seems to be the case) then good luck with that (and also the amount of R34 on the main character is going to be insane lol)
