Hello, first of all, iīm spanish so iīm sorry because my english is bad

Well, my idea is a basic tutorial of troops, i mean, when you unlock a troop, you will have a short-tutorial about the troop. In the tutorial will explain some statistics about the troop and you will attack a demo town to try the new troop. I think itīs a good idea but I donīt know what more i can add.
