The soundtrack or Indie Game: The Movie was available for pre-order two weeks ago and now is officially released! There were several bonuses for pre-ordering such as a nifty t-shirt and the album on vinyl, however don’t despair if you didn’t get that opportunity. You can still get all these bonuses if you order right now and pay more than the minimum price.
You can get just the soundtrack by itself for a measly five dollars if that’s all you’re looking for. It can be bought here, and you can even preview the tracks to make sure you want it before you buy.
If you don’t know a single thing about Indie Game: The Movie, you should definitely check it out on their official site.
