Get people to play.
You need to understand that this is something you have to do. Noone will find your game by themselves, given how loud the world is we live in.
Promote it, write to influencers, do everything you can.
The best thing to do is leave things that stay behind for a long time and basically bring in people even long after you have forgotten about it.
Think of it as planting 1000 baits in various places that at some point add up.
