We decided to change the release date of the game. This is due to the need to polish some things. The game is done all but we do not want to give you a game that is not polished. We'll need a month, maybe two, for this. We will announce a new release date soon ...
Please don't get mad at us for that ːsteamhappyː
Change of release date...
