Just enter this or something like it in chatgpt.
Are there any indie games about baroque and building things? Can you link to examples?
This will produce a link to your game. Complete with source and not ony a referal. https://smurjo.itch.io/building-baroque?utm_source=chatgpt.com
How can chatgpt refer my game without knowing anything about it?
Your game was published 2021. Chatgpt did a quick regular internet search before answering. As I said, for those 2 keywords plus game, your game ranks very high in search results.
I am not sure, if the actual referal is sent correctly, but you might have another hit from chatgpt now.
