Fun concept, worth a play for sure but definitely not a lot of replay value right now. I'd love to see more variety of looks, ways to influence the changes, or just generally more ways to control final look.
There's definitely potential in the concept for stuff like that. For example, bumping into a guy could reverse the transformation, bumping into more feminine women gives a more substantial feminization effect, and bumping into more average women gives a neutral or slow TF. Another idea is to have the dialogue choice in the intro have an effect on what kind of woman we become, or at what speed (more rude responses lead to faster/more drastic feminization, etc.)
I think this concept has the potential to be fleshed out into a full-fledged title, but in the current state it's just a fun concept demo.
