The bones are definitely there - this one has promise! The main thing that stands out to me at the moment is the feedback - it's hard to tell how you're doing, as sometimes the opponent visually stops spinning and yet still remains standing.
The mechanic of being able to influence the blade feels a bit hit and miss - and almost felt like it was detrimental at times. Trying to adjust your direction to aim for the enemy often meant missing, or seemingly stalling as a result.
Placing your starting position was cool, and helped to establish sort of strategy flair at the start of a match. It's unpolished, but it's still a pretty good prototype given the time constraints!
