Wow, this game has improved a lot since it's release in the 2 button jam. I remember having a pretty difficult time with the controls and being able to read the animations; though I couldn't help but be impressed with the spriting and the concept.
Now, the controls feel a lot more natural, and the animations better convey what my opponent is doing/telling me how I should react.
I'm currently trying to get through day 4, but only because I personally need to take some time to learn the AI and figure out the combos. The game itself has grown to feel pretty fair, and satisfying now!
