Buy the soundtrack?

[GarlicIsLife]

I feel I should have paid more for this stellar, sweet game. Seriously underrated.
Since there are some songs I adore (BGM 3, at least that's what it's called on youtube) is my favourite and I'd like to buy in in FLAC.

Is there a way?

Also, unrelated, but is the "Psycho-Horror" tag just a little troll to lure people into having a good-mental-health game? Basically a Doki Doki Literature Club but in reverse?
