The workspace is empty. It seems you want me to use this audio URL (`https://games.playscape.gg/html5-cEwfNo/assets/hakari_jjk.mp3`) as a "fever song" in a game, but there's no existing game here.

Would you like me to create a game that uses this song? If so, what kind of game would you like? For example:
- A rhythm/music game where the fever song plays during combo streaks
- An arcade game with a fever mode power-up
- Something else?
