>>713589063 (OP)bait controversy in a way your game is easily defendable or hated (tweak to what you preferred outcome is). you can either go niche (most people will shit on your game but your community will be extremely tight and loyal) or normie (mass appeal and generally liked but you have to constantly shill or the audience moves onto other fotm games).
setup a discord or something with monthly updates /whatever works for you and set roles to make fans feel involved.
bonus tip: make an easily findable youtube channel with dev commentaries or behind the scenes stuff (show a bit of personality), never market it and let your fans find it on their own. they'll find it special and endearing (as well as feeling like they found something hidden) which will help your audience find you more likeable and personable.
