Just finished the demo, and I really enjoyed it! The whole battle system was a bit confusing to me at first, but I got into it pretty fast! (Adding a tutorial about the battle system would be a plus later on though, cause at first glance Its really confusing). I really think Its awesome though, very different but alot of fun at the same time. I really liked the fact that you need to be on your toes aswell, or its pretty much game over. I cant imagine how the battle system would be with skills added aswell, that would be insanely sweet!
Another thing that struck me was your menu! Wow, Its absolutely fantastic!, and Adding the alt+ arrow shortcut was a very neat function. Also enjoyed the "battle map", really well done and works well for the concept!
Think you have tons of intersting mechanics, and I look forward to seeing your progress!
As for the story, I think Its promising.. even though the demo didnt tell much as it is.
Also, forgot the "skip cutscene" option! Thats something I would love to implement in my own game aswell, I have no idea on how Its done though, but Its a really neat feature!
Supporting this, and wish you luck on the project!
