As I said in a previous post, the team is currently working on a new update that will be available in about a month.
This update will include some new content

There will be available more levels for buildings, and troops. These are the new levels included in the new version:
Archer tower -> Level 13
Cannon tower -> Level 12
Wall - > Level 11
Catapult - > Level 9
Anti-aircraft tower -> Level 9
Soldier -> Level 9
Archer -> Level 9
Plunderer -> Level 9
Knight -> Level 9
Light knight -> Level 8
Canon -> Level 7
Battering ram -> Level 9
Healer -> Level 5
Furthermore, you will be able to build one extra wood warehouses when you build the Level 10 Castle.
The team is also working to be sure the game runs smoothly in iOS 11, which Apple will release soon.
Looking forward to your feedback on the new changes!
