Thank you, I'm really glad you love the update!
Your online shop idea would be fun. I'd definitely like to add new cooking options as time goes on, that link in with the various new systems.
I hear you about the fullness system. That logic stems from the original version of the game, which had no days of the week and limited you to one date per day per girl. I'd like to change it too at some point, but it may come at the same time as a wider overhaul of the dating system!
I'm currently working on a mini update that'll let you go through the blob milestones at home. One consideration is the growing space they take up, and adding new buildings to your home could be a good way to tackle this.
