With how little is currently in the story, I'd say daily updates or updates every other day for now might be best, that way you can quickly get more content in and become more likely to gather the interest from whoever sees the game in this infant stage. Quick updates for now might also impress some people, seeing that you're actively working on the project.
After all or most of the romantic interests have been introduced and the main setting has been established you could then go to gathering content and then posting.
