Merge Archers

Game description:

The kingdom is in danger! A huge hostile army is moving towards its borders, so everyone on this land must stand up and fight for their home. You are going to control a bunch of archers whose goal is to defend the castle standing in your enemy’s way. You need to place your warriors wisely around the map and make sure they cover most of the path your foes are going to use with their infallible arrows. You can also improve your fighters and even merge them to get new types of archers!
