This makes me picture a dark 2D platformer
Not sure if it was intentional, but harpsichords as instruments have no volume control - they're all the same volume. This has strengths and weaknesses - often the Harpsichord plays a sort of percussive roll, almost like it's a gentle form of percussion. It was cool hearing that instrument in it.
I think the mix ended up a little narrow, not really filling the space. But, it also still works. It would definitely work in a game.
Nicely done!
