Dear Friends,
As of recent achievements have not been registering on Steam for some players. This is an obvious frustration that we have attempted to remedy.
Moving forward achievements should be working for more players as we roll out the update across all platforms.
On top of this we've received some feedback requesting a windowed mode, so that has been added to the game as well.
We apologise for the inconvenience, and hope that with time these little issues will no longer impede your experience.
With kind regards,
Voyager, over and out...
