Click anywhere on the screen to move the army there. You don't have to wait until the army gets to the destination, it can be changed mid-process by another click. To modify the number of units in the squadron go inside the code and change the variable "units" to some value between 1 and 300. and restart the game.
It's a bit buggy for now. I'm working on ways of improving performance. If it gets stuck and never reaches the target, chose a different spot, and click or simply restart the program.
