This update fixes the problem with the Donor Achievement, which didn't get unlocked for those of you who decided to support us buying the Soundtrack.
To make it work, just update the game from GOG Galaxy and run it once. Get to the title screen, past the splash, and keep an eye on your achievement list. You should see it gets unlocked.
Thanks to all of our supporters for the patience and trust. It took a long time for us to solve this issue. Please, write to support@illiteratecode.games for any issue you may have with this new release.
