So, many of you asked us about Trading cards on Steam. This is a rather interesting question if you aren't a developer, so we'll reveal some working secrets to you: as we're an indie team that went through Greenlight, we have to wait for Steam to remove the restrictions from our game (Steam calls this "Steam learning about this game"), and this probably depends on the number of reviews or downloads (?). No one really knows how long it can take, it's different for every game and Valve keeps their rules details in secret. But as soon as this happens, we will be happy to add Trading cards to the game. We have already prepared them, drew badges and made 5 beautiful backgrounds for your profile. And about Emojis - we made them, too! ;)
The same applies to the Achievements. So all we can now is wait for Steam to finish its "learning".
