Because some games were marked as DLSite Exclusive, I shouldn't publish it on any location other than DLSite.
Yet, I share the same view on this point, I will contact DLSite to see if I can change the exclusive settings.
Meanwhile, you can still download the demo on DLSite without an account.
They are now available on itch.io and patreon, make sure you try the demo first (if any).
