We are in an era where the market is saturated with indie games, many of which are terrible. A large part of this is thanks to the low restrictions put on mobile and steam marketplaces.
So anyways, games are so common that people will not just try any game they can get their hands on. They need to think that the game looks fun to play.
I think the best way to get people playing would be to make a trailer video of a bunch of segments of raw gameplay stitched together. Go light on the effects and the dramatic flair, and give people an honest look at what the game is like. If the parts of the game that you show look fun, people will play on their own. If not, then they won't, and maybe that shows that you have a bigger problem (which is that your game is not actually interesting compared to the masses of other games out there).
