From what I read e few days ago on the dev's discord, he/she made all the music in the game.
If you want to download them, all the mp3 files have been posted in the chat channel of the discord (discord link in the OP).
Wow, what an interesting discussion here. I think first you need to check your computer for operability and Windows 64 bit is a must have... Everyone has some kind of problems - why don't I have them...
