In this lesson we learn about the bomb-ass data structure known as the array, the granddaddy of them all. We also learn about boring shit like the automatically-generated default constructor (BOOOOORIIIIING! NEEEEEERRRD!).

Homework
- Make it so that touching the poo is game over and the goal is to reach a square.
- Make the square's color pulsate and make a meter that keeps track of how many times the goal was reached.
The solution is given in this video.
