I had a soft spot for Lance and Gwen, and kept booking them to see if anything else would happen with them. Maybe in the sequel they can come back and get married (destination wedding at the inn?) / already be married and have a kid, etc. I really liked that our choice to book them together had an effect (I think) and maybe there can be more romances/ friendships that develop as a result of our choices of whom to book at the same time.
I also thought the detective characters were a neat way of providing hints in the game if needed. Perhaps add the option to pay for them to elaborate more on that specific answer once they've given the cryptic hint, just in case.
Also enjoyed seeing Wodehouse's cat around. Wish there had been interactions for it. While we're at it, with so many pets, the main character needs a pet, too, please!
