Ok, got to play with it for a few minutes.
A few comments:
The system seems interesting, and I can tell there is a lot going on. I like the complexity of the options.
The bad thing is, I don't know what is going on. There is this neat black box saying the last thing that happened to my opponent, but it doesn't always update. And it doesn't say what happens to me. I died without realizing that I was badly injured. Lots of white text flashed by, but it was hard to tell what meant what before it was gone, especially since the black box was more descriptive and I often paid more attention to it.
Also, the demo doesn't really say anything about the numbers for the characters. I see there are three bars in at the top of each character's stats, but no info on what each means. Also, no real descriptions in the demo of what to do or what causes what.
What causes an attack to be unopposed?
How far can I move and still attack?
What is the general probability of a given attack hitting? It tells me the damage I'm likely to do, I think, although one of my punch options was at -6.5 so...no idea if that means it'd do no damage or just a little. And no information to tell me if going for, say, a counter is more likely to be a good move over a basic stab to the torso.
