Well done on completing the game jam!
I like the idea of a dance battle type of game! I think the FPS parts of the game actually makes the game less fun. The FPS mechanics feel shallow, the enemies don't attack or in my play through just stood still.
I would suggest removing the FPS mechanics and make it a game about dancing (which seems like the more fun idea). To me it makes more sense that the player is "fighting" the AI when they are dancing and every beat that is "missed" damages the player and every beat that is "hit" damages the enemy (Something like Friday Night Funkin)
The controls feel very sensitive to me. This makes it hard to interact with the world.
I would suggest just scoping down and focusing on the core of the game.
But well done!!! Looks like a lot of work went into this
