First of all, today marks the official launch on Steam! If you already purchased Mixolumia on itch.io, you should be able to get a Steam key at no additional charge. I'm told you need to go to the download link in the email itch sent you when you bought the game, or go to this page: https://itch.io/docs/buying/already-bought and you can have them send it to you again. From the download page you can click "Get Steam Key."

Ok, here are the update notes:
