I'm sorry to hear that.... but I must admit there is indeed still a lack of content =/ We're currently moving the game to a new engine (which will bring a major graphical overhaul, but also more polished features in general). Once it's a bit more fleshed out, we will put a bigger focus on content.
Of course everyone who already owns the game will get the new version for free ^^ If you want to give it a try, it's currently in a beta branch on Steam - this topic contains more information about it: https://steamproxy.com/app/324080/discussions/0/3056237435828630015/
