Improved Antibirth OST for Soundtrack Menu
The built in antibirth soundtrack sounds kind of iffy in Soundtrack Menu especially with the repentance update, so this hopes to improve upon that. For a more complete experience, you should get All Antibirth Item Room Jingles as well as Updated Antibirth Intro alongside this.
Soundtrack menu automatically makes the Dross, Ashpit, and Gehenna songs not vanilla, which I can’t really do much about. If you want to change this, create a custom soundtrack and replace the songs from there.
