OK so I noticed that the Patreon rewards have changed and the method for getting them is different now. I'll go ahead and update y'all on what I can.
To unlock the new secret rewards area you have to flip two switches.
The first switch is in Trina’s shop. Interact with the statue on the left side. (Where Nova is standing in the first picture I posted.) When you do you'll be asked for a password. The password is “Fuck”.
The second is in the temple of the goddess. In the back there is a statue on the left you can interact with. (Where Nova is standing in the second picture I posted.) Again there's a password. This time it’s “Hard”.
Then a stairway will open in the middle of the treehouse area. (Third picture I posted, can’t miss it) When you go inside you'll see a whole bunch of chests. Each of them has their own password. The password for the bronze chest is “AsTyuhUP”. IDK the other passwords. If someone could crack the game and figure them out I'd appreciate it.
