Hello,
We have prepared badges, trading cards, backgrounds and emoticons. You can see in our store page that "Steam is learning about this game" text is written. Once this text is removed, trading cards and other community items are going to be enabled. But more reviews are needed to achieve this. The exact number is hidden and there are more factors to this, but from my experience I am guessing that we will need at least 80 reviews.
If you want trading cards sooner, please write a review for Mokoko X to help us publish them.
