/// UFO ABDUCTION ///
// Created by: Eyan Howlader
// Abduct all the cows as you fly your UFO through a farm!
// WASD to move the UFO
// If you fly your UFO too close to the ground, your game will be over
// Click and hold a mouse button to begin your abduction process
// Your Abduction Beam only activates when you're a certain height directly above a cow
// You must completely abduct the cow into your ship in order for the next to appear
// If you let go of the mouse button midway through abducting a cow, the cow will start falling down!
