Don't Panic is a simple endless runner with frustratingly ridiculous controls where you must try to get as far as you can safely while avoiding other people, looking out for environmental changes, and seeking out the coveted loo rolls.
Use the joystick to move left, right, forwards, and backwards if you really must, to avoid obstacles and the waves of idiots running at you.
If you find a loo roll, grab it as it will help you get further, but don't be greedy! You will be sent back home if you take more than you need.
Pay close attention to the doorways to shops, and only go when the light is green. Only stupid people enter when the light is red.
