Hey guys,
In December we updated the game with two new levels (one in the Sky Keep Courtyard called Sky Keep Prison and one after the first Boss Fight called Floating Citadel). You can get to both of them via level select if you have previously completed the game. We also added many bug fixes and optimizations.
We didn't do a big announcement as it's not a massive amount of content but some people mentioned that the game did not look updated since June of last year. So if you haven't played the game since then you will find that the Sky Keep Prison area gets the game going with more combat early on and the Floating Citadel gives more enemies to use the God Axe against.
Hope this helps clear things up!
Cheers,
Blake
