Wow! Thank you very much for your time, I am honored to receive such deep and constructive criticism for the game.
There are some issues that I could not review in depth due to lack of time, but that I definitely want to correct.
I had planned to add the Army Unit button, but couldn't finish the mechanics, I was also working on a prototype for battles.
For now, I am going to correct the bugs you tell me, and I just want to say, that I really appreciate all your comments, because they will help me improve.
