I should add, why I asked was because I didn't know if I keep them on the page with my paid games, if that means since it will have a free demo (not even sure if I can set the demo to free on the same page as content set to paid), but I was asking would it get listed if it is on a page also with paid content.
So, in case, based on how you are kind of coming off, let me make sure you understand, I am not ignoring your advice or typing any of this with any kind of vitriol or meaning to come off any anything less than grateful to you, but after 12 hours looking into this I am learning a lot. It sent me all over the place, but the more I have learned the more it looks like setting a separate page as a demo appears to be the cleanest and most likely to get people to my paid games (which makes money for Itch too, I've paid thousands of dollars over the years, I could have kept, and chose not to do so as an honorable person).
