Watch out for open manholes or Charley will fall in and lose a life!
Keep an eye on the colors of the chefs. When the chefs are blue or yellow, they can't hurt Charley.
In the higher levels, have Charley race to the cone immediately for the high cone points. You win an extra 500 points each time Charley scrambles to a higher level.
Use leftovers as ammunition whenever possible. Remember: if Charley's carrying food when he reaches the cone, he takes it with him to the next level.
