I tried to continue my IslandQuest game, but the screen can’t open the game. When the screen opens..

I tried to continue my IslandQuest game, but the screen can’t open the game. When the screen opens, the picture/screen is half dark and half light. The top of the screen says “Find the door to the room containing the levers”. The screen is frozen but it allows me to purchase coins/ rubies. The characters don’t move, and the screen doesn’t allow me any options except to buy coins

Help, thank you
