A game, where you need to use your phone to find a signal to transmit a message.
DD87 is the name used by NASA to call the Spaceship that performs a mission to the Moon.
The DD87 was flying through space when suddenly a large meteorite hit it, and the main antenna was damaged and communication with Houston was affected.
The captain is wounded and you are the only hope to ask Earth for help. You must find the signal to transmit the information.
You need to use your phone (with the gyroscope) to find this signal.
The future of this mission depends on you.
