Use joystick or WASD or arrow keys. Press space or the button to on the bottom left to fire a missile. Press the r key or the middle button to fire the machine gun. Press the button on the left or press the f key to fire rocket. For touchscreen players, do not hold the fire buttons, just tap. It might take a few fires before the aimer will stop going to the fire buttons when you want to fire.
Thanks to Griffpatch (I went on YouTube for his channel) for the joystick. Thanks to my sister for some of the art. For the rocket explosion picture, I searched on google. There is a bug when the aimer will go to the fire buttons unexpectedly. Read the instructions if you don't want it.
