Our patch on Friday included lots of new details and content for the in-between worlds. If you haven't seen them yet, jump in and take a look. There are some fun Easter Eggs to find.
We are currently working on getting the last level ready for deployment. Level 20 out of 20 (not including all of the 9 or so in-between worlds).
A lot of people have been asking what the date for this is. As soon as I know there will be an announcement as this will also mean the game will officially go into Beta. It shouldn't be too long to wait. I shall be poking the relevant people with a sharp stick and will report back :)
