Rock Paper Scissors Challenge. A classic game evolved..!

Your mission is simple. Protect the city and destroy every enemy as soon as possible!

You have a group of possible weapons represented by Rock-paper-scissors symbols emulating weapons in real world warfare.

But not too fast!, your ammo is limited, and your enemies multiply quickly..

Rules / How to Win:
Avoid any direct hit to your tank
Destroy every UFO out there. UFOs require 3 impacts to be destroyed
Protect the city. Buildings require 3 impacts to be destroyed

Bullet's symbols play a big role. You need to fire the correct bullet every time if you want to stay alive.
