It shows a black screen – Classic Snakes and Ladders Review

When I open the app, it just shows a black screen until I tap the screen. Then the screen is black on all the buttons. When I press "play", it just shows a black screen again, but I can still "roll" the dice because I can hear the animation. Can you fix this? I have a ludo app from this maker and it works perfectly fine, so I don't know why it doesn't work.
