I'm just one of the few Game Developers here at CodeCombat
But! If you want to see how often CodeCombat is updated, hop by the GitHub. All of our other developers contribute there and you can see just how alive it is!
For the first quarter of 2017 the actual game team has been working on, such as Pets, the Announcement Modal, and the improved hero unlock mechanic for our premium users.
Very soon we're going to start planning what we are going to do for the second quarter of 2017. We're always keeping an eye on the forums for new suggestions, and we haven't forgotten about the Volcano world.
