Soundtrack Sound effects Bosses Monsters


The Paper Isaac soundtrack is composed of fan covers of the original Binding of Isaac game. All tracks were originally composed by Danny Baranowsky, and were covered by 10 different artists!

The effort is tracked on this Google Doc. Hit me up on Twitter if you want to contribute!


Why are you doing this?

I’m doing it as part of the OneGameAMonth permanent game jam. Also because I’m a huge Binding of Isaac fan, and also as a gift from the BoI community to Edmund, who thought nobody would like this particular game!

I asked Edmund, who seems to be cool with it. Nothing has been ripped out of the original game, every single element is hand drawn, every song from the soundtrack is recorded from scratch, every enemy is programmed ex nihilo.

Is it free?

Of course! You’re encouraged to go buy the original game, and Rebirth whenever it comes out.
