“like a laptop”“Screen is good, more viewable and clear”, “Small screen”“perfect aiming in phone”

“like a gun”, “like remote control”“Big-bright screen”, “distorted screen”“Its easier as joystick needs to be moved, not pressed. There is something in

centre, and we can move Left, Right, Up or Down”“joystick not so accurate”

“I like to spell, spelling is good”“stars and rocket going up is really good”“I love to compete… winning is good”“… nothing specific about the game, I just like playing with my friends”
