I would want it to be open source!!! And if there is a way to clone releases in github then updating wont be a prob as I can jus get the latest release with some commands which I may automate too!!!
Have an Idea!!! I will fork your repo and add the releases to it myself as soon as I know about a new version!!! I dont know C# or VB so I wont be able to compile anything but at someone can do that!! If You want u can start uploading releases to github along with itch and this will help me and maybe someone else !! But its ur choice
