Just a little capture before the futur redisgn of the control + gameplay.
The actual control version based on mouse isn't nice and precis for mobil.
The futur version will have static zone/place for the tower (construction place) and you will EMP power (energy mental power) to mix the gameplay phase, the control will be 1 touch per action (no drag control).
1 - construction tower like a classic tower defense
2 - action when you see your tower do the job
3 - interaction with the EMP tower to protect/heal/boost/attack too using you finger ;)
