Now that we have all the elements in our game, we need a script that makes our character intractable with the other elements in the level, and that takes care of the level logic.

To do this, create a new C# script and name it GameHandler under the folder Scripts. Then, attach the script to our Player object. Double-click on the script in order to open it.

First, we need to define a lot of variables. Let's start with two to keep track of the player's score and health:

    public float health = 2; 
    public float score = 0; 

Now we need a variable to check if the game is over:

The next step is to implement the logic behind the collision of the character with an object. This can be done by using a function called...
