Hello there! Auden here. I hope you're doing well.
I'm happy to say that Find Love or Die Trying Rebuilt edition is now playable in Spanish!
To play the Spanish version, make sure your language setting is set to Spanish - Spain or Latin America before you start the game. If you had already installed Find Love or Die Trying with a different language setting, try reinstalling the game to make sure Steam sends you the right version. The Spanish version of the game will include the ability to toggle between all supported languages, but other versions will not have the Spanish translation.
The game should start without any extra steps on PC and Linux, but there may be some issues running on Mac due to recent malfunctions with Apple's notarization software and certain versions of macOS. You may need to manually grant access to the app to run if your OS gives you an issue.
These steps should be able to help you if you run into issues with playing the Spanish version on Mac: https://support.apple.com/en-ca/guide/mac-help/mh40616/mac
Hope you enjoy, and thanks again.
Sincerely,
Auden Cho-Wong
