Hi

I have recently put a print and play game up on itch.io for free and I am looking towards using itch.io for both digital and printable games including paid DLC for both my printable games and digital games.

How does DLC work?  Does it need to be a new page or is there a way to add it on the same page?  

Also can I give people paid DLC for free?  Some people helped me by completing surveys early on in development for my game series and I'd like to be able to give them everything for free, including the paid DLC as I publish it?  Is it possible to do this on itch.io?
