The HOMESICKNESS Original Soundtrack is now available — currently discounted at $3.59. It features 29 tracks, including reprise versions of "fifth stage," "cog," and "memory." If you're interested in owning the game's OST, be sure to check it out while it's on discount!
The soundtrack will be available on streaming platforms later down the line, so do keep an eye out! Thank you to everyone for the continuous support — I'm actively working on possible future releases. :)
