But I personally would like to allow people to download ‘dev’ versions of the game specifically from a devlog post, without them ever showing in the game page.
You can add a “stable” and an “unstable” version of your game on your page, and link the unstable one on dev logs, that have experimental features. This way you can keep working on new things, and show others your work, while also having a stable version for people that just want to play the game without many distractions.
