To begin with, i was only able to play by myself, but I find this concept so cool. It's such an elegant use of the 1 button prompt, creating a really intense momentum driven fighting game. Even just by myself I fun swinging around the zone trying to manuever around as quickly and as competently as possible. I only know a little about Capoeira, and I would be really fascinated to hear how this acts as a streamlining of the art, cause it definetly feels like a strong distellation of a larger concept.
If I have one complaint, its that it wasn't always easy to know which player will win in a fight. I can't tell if I was just getting confused or playing poorly, but the player I was expecting to win often wouldnt. I know your meant to hit the pivot point, but sometimes it felt like both players hit eachother's at the same time, or none was hit at all and still somehow someone lost. Again, my solo play limits my understanding, but fine-tuning how that works (perhaps with some invincibility frames) or how its presented would help alot.
Overall this is just a super elegant concept executed beautifully. Well done!
