I don't know how this got past me, but the music quite literally stops after some time. I made it down the the final screen below and the music cut out and all that was left was the sound effects that the little dividers made when the balls touched them. That needs to be patched Asap!
... that was a design choice. We wanted the music to stop when you were contemplating your question.
I'll modify it so the music quiets down rather than suddenly stops. I'll convene with the artist and see what she thinks. One man's feature is another man's bug. If it looks like it's broken, I'll change it so it looks purposely done.
I want to revisit the music altogether! People who play through the game say they got sick of the music (and the developer says this too ;) but once upon a time I had the idea that each page would have its own music. Time to get on that!
