Been here since version 0.3 and still can say one of my favourites. Been through most adult games on here and it's definitely in my top 5.
And i agree with your thoughts, i think quality over quantity, focusing on a girl fully seems better rather than trying to make a big cast. The current cast seems fine too, so better to get the important things done first than already tryna introduce the next girl.
One thing i was wondering, if you considered different clothes/dresses as option for the girls. Maybe like, as unlockables per affection or as special gift. Granted it wouldn't always work in scenarios like Molly when she just came from work, then she would have to stay in a suit, but still.
Edit: of course i don't mean to give you even more work, that's just an idea for when plans are finished and you feel the cast is done well enough that you have the time and resources to do polishing and side things.
Just wanted to say really appreciate your work. The writing also is peak and i won't lie the petting scene with Alice (i think her first h-scene) awakened something in me lol. Really happy to have found this game.
