I'll tell you a bit about what I'm working on right now, so you don't lose track of me:
Right now, I'm working on the main gameplay cycle and the UI for the end-of-day summary. The main cycle involves checking documents. You start the day, visitors come to you, and you either let them through if their documents are in order, or send them back. I think many of you are familiar with this mechanic :) Each location will have tasks available, and by completing them, you'll earn stars. These stars are needed for career advancement. The higher your rank, the more authority you have (especially in interactions with girls =3), and you'll unlock more challenging locations.
Art with the girls will come later :) I'm not the kind of person who can spend an hour on one task, then switch to another for an hour, and then switch to a third. Usually, at the start of the day, I load up all the resources in my head for completing one task of the day. For now, I'm working on the less flashy UI.
