Looks great! The dialogues are well made, the visuals and the soundtrack(s) as well :)
I sadly did not get too far because it was a bit too hard, in my opinion. I would probably increase the time in which they're vulnerable, since 0.5 seconds isn'r really enough..
But other than that, it seemed pretty decent. But then again, reduce the difficulty a bit and also try to make the dialogue in the fight less distracting, I have to look completely away from the fighting scene in order to read it..
