People thing they can only tap on the square.

Describe the solution you'd like

Replace the text to "Tap anywhere to start" to make it clearer you can also tap on the background (easier to tap, as the square is in the center of the screen).

Describe alternatives you've considered

In the future, you could have the square moving the place you tap to make it clear that anywhere will work, I don't know, to think about.
