In this simple maze game, the player has to navigate through the maze, while avoiding enemy NPCs. The application is experiencing some performance issues, that you will need to address. The optimization routes taken in this project are common throughout many Unity projects and understanding these techniques will allow you to optimize your own projects.

1. Use the Profiler to identify a problematic performance
    a. Open the Profiler in Unity, by going to Window > Analysis > Profiler.
    b. Play the game and observe the performance profile using Deep Profile if necessary
    c. Identify the AI Behavior as a hindrance to performance

     d. Record the profile data to use as a baseline (never optimize without a baseline)

 1. Optimize the AI Behavior
    a. Open the SimpleAI script
    b. Determine the problematic section of the code

    c. Fix the code section by commenting out the culprit

1. Use the Profiler to analyze the results
    a. Open the Profiler in Unity
    b. Play the game and observe the performance profile
    c. Compare to your benchmark
