Nice one. I really appreciate the mechanics so scored higher despite you running out of time with wrapping up the win condition. The world needs more audio-based games. I saw from your other comment that you have some music production experience - maybe lean into that!
On my submission I loaded a bunch of FMOD randomisation, DSP and looping into my game for the sound effects and music... And then learned just how 'exotic' the solutions for getting FMOD to work in WebGL, 1) at all and 2) without hurting eardrums.
