Thanks for checking out our game and the feedback.
Regarding highlighting where the ship has to land, when you have a ship selected it's landing zone will flash(clicking and dragging on it). The effect is a bit too subtle to notice right now. we are planning add a more visible highlight effect
As for having visuals where ships will collide we will think about it but I feel it will make the game a bit too easy. there is already an indicator when ships are about to collide.
Regarding the pause button there is already one in the game. But I think you mean without the panel so you could see where your ships are going. we will definitely consider this too.
