The game is not yet officially released on Steam, and Early Access games get far less exposure (also many players don't want to buy an unfinished and potentially buggy product).

We are very close to the release now, and we really hope that it will give the game the exposure it needs.
These things need timing as well as luck - But, of course, showing activity on the forums and adding screenshots and clips to the Steam community section will help show the upcoming new players the potential and quality of the game.
