At first it felt a bit confusing because i saw the yellow ground, but i was not sure for what it was. In one action it was for moving a unit, and in the other for the turret's action. I think separating types of actions into different colors for that could make the gameplay feel smoother and easier to catch up. In example since the turret is a offensive action, instead of yellow, red. That's the sort of thing that i've meant. Nonetheless, this is a well polished and a very well-executed game, and fun to play!
