This game will be based on the first chapter of Through the Looking-Glass, in which Alice attempts to wind a ball of yarn but is interrupted by her cats.

Milestones:

• Create background that resembles a sitting room, possibly using an imported image.
• Create Alice turtle (probably blue). She will be the active character.
• Make Alice respond to keyboard arrows.
• Create a class for the cat objects. They will be the same shape (turtles or possibly imported images) but different colors and, ideally, different sizes.
• Name three cats. Dinah is large and black, Snowdrop is small and white, and Kitty is small and black.
• Design an object to represent the ball of yarn. It will be a gray circle.
• Make the cats move randomly.
• Make yarn move when cats intersect with it, leaving string train (yarn.pendown).
• Have the yarn spawn smaller gray circles and leave them behind.
• Have a way for Alice to wind the yarn again, possibly using yarn.clear (individual clears for the spawned balls).
• Have a counter for the number of yarn balls picked up.
• Trigger winning sequence when counter reaches 10 (or whatever number seems to best fit the game).
• Design winning sequence in separate module.
• Optional: Give user the option to restart the game.
