Thanks! It took me a while to think about this mechanic, and even longer to implement and simplify it. So it's good to know that it's being useful.
Well, I make my assets available as a way to be as accessible and versatile as possible. There are no intentions of receiving anything in return, even through donations. In addition, redistributions are also allowed within the limitations of the license, so I hope you understand why this option is missing from the page.
I admit that I want to play more games using this feature. So good luck in your work!
