Can I ask why the public codes are locked behind a Pay wall on Patreon?
Because codes are for Patreons. They work on the public version yes, but only because that's when I update the cheats. The cheats don't just work every update, for example the secrets cheat needs to be coded so it includes the new secrets that were added that version. Since the public release is the final build where no new content will be added, there's little point adding codes to Patreon builds where new content may be added after changing the codes, which would mean they need changing again.
As for why they're Patreon only, because my Patreons deserve some extra perks for supporting me. They're the reason the game exists, if they didn't support me, I'd have to go spend way more time doing another job and not developing the game.
