A visually appealing sim with quite a bit of nuance to making the matches! I like the drag and drop interface, but it took me a bit to figure out how it works, a tutorial or highlights for draggable areas would help things a bit. The idea of the dialogue tree is attractive, it just needs a bit of clarification. I've encountered a few bugs with characters disappearing or duplicating, and the music stopping. Lack of explicitly sexual scenes is probably what feels the most missing since the game doesn't shy away from adult themes in other areas.
I think you're very much on the right track! The fundamental mechanics are new and interesting, and the controls feels fun to use after getting the hang of them. Nicely done!
