Joe Aquiare, the composer behind Khimera: Destroy all Monster Girls has put high-quality MP3 versions of the OST up on Bandcamp for purchase. A few people have been requesting this, so he made it a thing that you can check out right here:

I've also gotten a few asks about trading cards and yes, these will absolutely be a thing! I'm finishing up the assets over the weekend and the full trading card/badge system should be up at the earliest, Monday evening.
Thank you friends for continuing to support Khimera with your comments and suggestions over the past few weeks. I will continue to do my best to bring entertaining, quality games to Steam!
