Good AI but super short story. Personally, I'd rework it with a slower build up. If the dev learns AI animation this could be a really good foundation. The model is super cute and she could be the star of a longer VN if the dev chooses to go that route. Solid start, but really just a demo at this point.
Version 0.12 Update
===============
Dialog and narration remain strong. Dev is building the characters and interactions well, and he clearly understands both the essence and subtleties of a structured D/s relationship. AI is top rate, but the Dev may want to consider new locations, poses, and positions in his next release. Generating superb images that fit the story line is definitely the main challenge with AI, but this Dev is off to a great start. As I mentioned in my original post, animation will be needed at some point to achieve S-tier status.
Version 0.14 Update
===============
New art style. Sorry, but you lost me. Much of the original appeal was the tasteful use of quality AI images. I'm out. Downgraded to 2-star.
