This was mildly like something out of a fever dream. In a good way.
Laughed when the music started becoming more intense, especially with the clown's face/animations. Absurd but creepy.
I have a massive soft spot for "Hall of the Mountain King" though, so you get extra points for that.
It was a little difficult to read which attacks were hitting where, but once I had figured it out through trial-error I was able to play the game as intended.
A similar build-up with other mini-games and a narrative that gave the mini-games weight, would have had me more engaged.
Good job on this, it's made me think of the possibilities of absurd mini-games paired with classical music.
(EDIT: Also, my team submitted quite a similar mechanical concept, in terms of player/opponent attacking/dodging with rhythm in mind, so it's cool to see other people are in a similar mindset.)
