Looks like it falled back to tap to beat mode for you due to some audio reading issues. Normally it listens the audio and finds the bpm automatically. If you can check the developer logs and send a bug report, I can have a look at it.
Add a debug=true in the local storage if there is not much logs.

I created a new Chrome profile, installed extension, and this time it autodetected:
[INFO] DanceJump: Tap-to-Beat enabled (fallback mode) - UI hidden until needed
game.js:35 [INFO] DanceJump: Beat Tracker enabled - attempting audio analysis
game.js:35 [INFO] DanceJump: Background Tracker Started successfully

Feedback:
Default steps were pretty simple, the "arrow" on the right only lets you pause/unpause. I couldn't figure out an easy way to crank up the difficulty. You might even consider an auto-increase of difficulty. As they get more correct, increase the density of arrows as the song progresses.
It also says "tap to ARROWs" (typo "tap the ARROWs"?) but there aren't any arrows to tap either.

Couldn't get beyond this screen unfortunately.
Slightly related, there was a VR game (that unfortunately got absolutely buried under the significantly more successful Beat Saber) some years back called Sound Boxing that let people create step tracks to songs on YouTube, and you would punch, duck, bob, and weave to the beat. I absolutely loved it.
