"Coming soon" means that this game is in the Alpha/demo stage and not in the "Early Access"/mostly playable stage! Those downloading it should consider it as a "preview" of a game that may be worth looking into! For more information, see here.
Don't worry. I don't doubt that you or anyone else here will get the chance to enjoy the finished product once it's ready to be finally released! It's only a matter of time ...
