Use the arrow keys to control the girl in the maze, get the stars, avoid the ghost and the beetles. The beetles will hatch from purple eggs, the eggs won't harm you but act as a warning that the beetle will hatch there, so avoid them. The game 'levels up' by changing the maze at certain points. there are four levels. Sometimes Trisha is standing in the wrong place when the maze changes, and gets stuck in a wall, so <space bar> will move her a bit to free her.
@thehagus1 wanted me to go through the steps in the game 'Cheese Chase' in the 2015 book 'Computer coding Games for kids' Carol Vorderman; Dr Jon Woodcock, published by Dorling Kindersley. I changed it a lot especially at the project part when they add the beetles. I wanted the beetles to hatch from random places. I had to learn how to work around the sprites getting stuck in the walls, and also how to get the beetles to negotiate their way around the maze.
