I teach game development and I would like my students to upload their homework to a place where I and the other students can easily see it, so that I can comment on it along the way. Itch.io seems to be a good option, as it allows anyone to download games and make them instantly playable in the browser. However, there are several potential problems:
Even if it is allowed, I am not sure it is good for the reputation of students to download such half-created games. Ideally, it should be possible to create, for each game, a URL which is not published on the itch.io website, but which can be opened by anyone who owns the URL. Youtube.com has such an option. But I didn't find this option in itch.io. I only found three options: Draft – which is only available to the owner, Restricted – which only allows downloading (do not play in the browser), and Public – which is available to everyone but can also be found in searches in itch.io.
So my question is: is there a way to use itch.io (or another similar service) to download drafts of games, so that drafts will be available for the teacher and for the other students of the course, but will not be published worldwide?
