It's amazing, and really fun. However, I can't help but hope that the controls will be more customisable later on, as parrying with right-click seems hellish to me. I just can't wrap my head (fingers?) around it.
That aside, I absolutely love the pixel art and dialogue portraits. I'll be keeping an eye on it, if the demo is so good, I'm sure the full product will be a banger. Oh, while I'm at it, gotta say, the music fits the battle like a glove.
