My god you are horrible developer. Why would you lock everything behind patreon?
The fact that you can only unlock 1 character by using devotion unless you are a patreon. Why are you even bothering uploading game here if you are locking it behind code? What is the point? God damn it EA would be proud of you. Jesus christ.
DO NOT BOTHER PLAYING THIS SHIT!
There is no locked content whatsoever in the game. You can get all the current progress with any character as if you were a patron, only difference - patrons get instruments to get that content easier. That was my idea of getting support, I don't want to lock out content, like extra characters only for patrons, or extra scenes.
If you mean that you can only devote to single person - it works the same for patrons. That's why it's called 'devotion', it's not a typical corruption game where you can romance everyone at the same time. And once you've explored someones path - you can load a save before devotion, what patrons will have is an option to drop progress to the point before selecting the character without bothering to save. That's it.
