The prototype/proof of concept is independent of the version actively being developed in the dev log. As explained in dev log #1, the game for download on this page is just a proof of concept. Future dev logs will have more specifics on the game, which builds on the concepts in the prototype. Previews of the explicit content will be Patreon/SS-only.
We do not plan to release the finished game piecemeal, as is the norm for 18+ patreon games. A new demo will be uploaded when the full game is complete, with the current version of the prototype included as a "legacy demo." The full game will be released in its entirety with small bug fixes after the fact, if needed. This will result in a slightly longer wait, but we are actively avoiding the current Patreon model. (You still have option to support us on Patreon or SubscribeStar if you like, though).
Hope this clears up a bit of the misunderstanding.
