Thank you for your comment, there is a description about the shards when you hover your mouse to the shard icons on top. But maybe it wasn't the best place to put it. Thanks for the feedback.
Oh man I really didn't realize that I'm sorry. It's very nice that you thought of that and put it in the game but you're right, putting them in a more obvious place would be helpful for players like me who didn't think about hovering over the shards
