Hint: If you expand one of the button objects in the hierarchy, you’ll see a “Text” object inside - you have to edit the properties of that “Text” object
Hint: OnMouseEnter() detects when the mouse enters an object’s collider - OnMouseDown() detects when the mouse clicks on an object’s collider
Hint: When you set the score text, you have to add (concatenate) the word “Score: “ and the actual score value
Hint: In the GameOver() method, make sure the restart button is being reactivated
Hint: There is no information (or parameter) being passed from the buttons’ script to the Game Manager’s script - you need to implement a difficulty parameter
Hint: Google, “Unity Count down timer C#”. It will involve subtracting “Time.deltaTime” and using the Mathf.Round() method to display only whole numbers.
