Amorous Dezign
A little late to the thread but anyway...
First congrats for your game, haven't played yet but looks great.
You should take a look at
You must be registered to see the links
since he is the master in promotion.
Your patreon page is also your advertisement page.
So at least once a month post a small public message e.g. with an unfinished or censored image of the event you are working.
And at until you begin to have a large number of patrons do not hide the stats (only their number). People usually tend to join easier crowded places (shops, bars, restaurants, etc.).
I don't know if patreon allows a "0$" join-in tier , but if it does at the first 3-4 months you should activate, it in order to attract more people.
wish you best of luck.
