I think this was one of the best games in the jam I've played so far. I really enjoyed the combination of boxing game with rhythm game mechanics, and good picks for the music too! The art is really great for the various characters in their different poses, too. The 3D-aesthetic works for the background I think. I think I can manage 6 inputs, but with 8 I lost track, and was not able to complete the game after a few tries of getting back up.
A few issues though, even though everything else is so good; I wasn't able to click on the main menu buttons for starting the game, I tried with multiple browsers on my desktop and my laptop. But the windows version works just fine. I also sometimes was in a state where I could not dodge because my inputs were ignored. There was another issue where the numbers would quickly chain-reaction trigger as "missed" way too quickly when the indicator was not yet in the center.
But great job, what a nice game!
