We're still mostly focusing on walls and siege units, but while we're at it, we wanted to upload this minor polish patch for 0.6.3.0, that adds a few improvements, balance changes and bug fixes.

Progress on walls and siege units
Walls, gate and connections between these and watchtowers are now fully implemented, so we've moved on to siege units. We've come pretty far in adding siege units as well (you might spot a new building and unit in the image below). So while progress has been slower than usual because of paid work, life etc., lately, we're still making steady progress towards the next content update. The image below is also showing how walls, gates and watchtowers can be connected.
