So you know how on pages users have the ability to enable community? My suggestion is there should be a option to enable a in-itch.io issue tracker. Gamers can create issues in the issue tracker about bugs they encountered in the game. The developer or admin can create categories and mark issue statuses . Admins can also create millstones which list all the completed issues and open ones and how close they are to reaching the next versions. Similar to github milstons.
