The game does not seem to start when clicking the Start button. Does the game work for others?
Also, I noticed that the Start screen is not fully shown if the game is not in fullscreen mode. You can fix this by changing the settings of the game on itch.io: Edit Game -> Embed option. Increase the Height value so that the whole game screen will be shown or alternatively select "Click to launch in fullscreen" as shown in the image below to make the game only playable in fullscreen mode.
