Wasn't really engaged. Intro cinematic is cool but without colors its kinda messy - could barely understand what's going on. Also doing the "I don't deserve to live" couple of seconds before the "I'm a magical girl" and "here have my power" is a bold move story-wise, but it also got me disengaged really fast.
Combat works. It's alright, reminded me of old flash games. Didn't really see the point in doing combos or whatever since spamming auto-parry and the very first attack worked.
It seems that every time there's a screen change - some input lag is introduced into the game. I got close to 1 second of lag.
