Thanks for the feedback!
You aren't able to use the exit game buttons?
We aren't marketing the game yet, so people are only finding it organically. You can join our Discord and give yourself the role of looking for a game, there is a sunday hangout and play channel, and the community is holding a casual tournament (Crescent Cup) on 19th of December, so hopefully you can find someone to play.
The reason the game is still free, although we have already spent a considerable amount of effort in polishing the base game, is that it currently includes a demo mission and functional multiplayer. We'd like to include more single player content before we consider charging for it.
