Currently for some anomalous reason it seems that creators are not actually notified if their game receives a star rating. Considering that the rating system is an integral part of a games image, and some players will put all their feedback into their rating description; creators really should be notified of when one is made. Or at least have a toggle option for it.
As it is now, we only discover that our game received a rating if we're checking the analytics and noticed there is a new one. And sometimes, players have left all their feedback in the rating description; which goes completely unread by us until we happen apon it randomly.
