Hey! I'm really glad you’re enjoying the game, and it's awesome to see fellow Skyrim fans like me appreciate the world I've created. And yes, I do work on the game alone, and I dedicate a huge amount of time to it—most of my free time is spent thinking about it.
As for your second question, unfortunately since Itch.io stopped featuring NSFW games that offer purchase options (even optional ones), Patreon has become my only source of income. However, you can still support me by recommending the game to other players on forums or elsewhere.
