I think I remember it started off as the male MC coming back towards his hometown (by train?) where his sister was waiting. The sister planned (and her bf went along with it) to transform the MC into female so he can have fun and not be boring. MC had the option to send a boob photo to his friend, go to a club and even flirt with his sister's bf (or watch them fuck). In the end, he and his friend went to a swamp (?) where the witch resides to break off the curse. I don't really know what else to tell since it's really been so long. I think the last update of the dev was to change the UI (?) into something orange. Maybe I'm wrong about that tho.
