Use the mouse in order to move from right to left and in each side and the shooting will be launched by you only if you shoot, by tapping on the game screen. This is not going to be easy at all, because you have to focus and then you should start take caution, achieving new skills with the earned money because the goblins will become stronger and stronger and their waves will be more and more powerful but you will still be only one. Good luck!
