Problem with PlayGameButton

I have problem with Play Game Button in Squashy Toad Project.
I followed the instructions step by step ( in Unity Version 2018.2.3f1 ) about the Squashy Toad project and I faced problems on Play Game Button.
It doesn’t change color when I hover on it (with Alt+mouse) as a result it doesn’t change the scene (when I hover on it)

I don’t know what’s the problem because I have already adjusted the Start button to the size of the text.
I am sorry for my poor English.
I am waiting for your help.
