I like the idea and choices you want to implement so far. Maybe make a few basic choices and make things unlock able via story and different routes thus adding to replay-ability. You could probably add this for other guests too, which could then be unlocked for a changing room feature for who want to see a mix and match or all the sweet swag or lack of for their enjoyment. Love the story so far and the music along with it. Makes for a great feeling and it makes me excited for what else is to come.
