The dynamic soundscape is delightful, as it subtly adds instruments and musical texture as you progress. And going back down the scale regresses it to simple again. Smoothly done.

It reminded me of Operation Neptune (1991): each level starts with just one channel, probably percussion, and as you progress through the rooms it adds and removes more channels or sometimes switches to a different section of music. It is unfortunately all sharp cuts, no attempts at smoothing or timing instrument entry and exit. A couple of samples: https://www.youtube.com/watch?v=S0LNaatyoQk is an hour of gameplay revelling in “the dynamic and sometimes beautiful music of Operation Neptune” using a Roland MT-32 MIDI synthesiser; and https://www.youtube.com/watch?v=wPxEdQ4wx9s&list=PL3FC048B13... is the PCM files used on some platforms (if you want to compare that track with the MT-32, it starts at 28 minutes).

Man I played Operation Neptune a lot when I was a kid. I wonder if it was the first game to do this style of adaptive music layering. It predates the iMUSE system used in LucasArts games like X-Wing and TIE Fighter.

For anyone curious, you can actually play it here: https://archive.org/details/msdos_Super_Solvers_Operation_Ne...

The arcade classic Space Invaders had a primitive soundscape in that every time the remaining invaders advance, it plays a short bass note. As fewer and fewer invaders remain, it takes less time for them to advance, and the note repeats faster and faster, it adds a remarkable amount of increasing tension as each level progresses.

So not exactly the same, but perhaps prototypical. I think Asteroids did as well.
