He does. He has some on his Patreon page or the "other" site. They are called "Room for Rent", "My best friend's daughter" and "My first love". But they're grindy as hell with a semi sandbox (choice based) and without real hints. The most of hints you get from the dev themself, is to read the story, because there are supposed to be hints in the dialogue. But my own experience has shown, that the "hints" aren't obvious or helpful. I don't like the games very much, especially in the later stages it gets really close to sharing and/or whoring the girls out without it happening in the end in some of them. In "my first love" there are other guys with the girls involved, because the MC films porn until some point. Just to make you aware. Also, the MC is every time the same with a slightly different age (this here not counted) and loses his LIs at the end of every game.
