CISRA Puzzle Competition 2011 - Hints

3C. Om Nom Nom

• It's possible to make the ghosts get stuck on the bottom row. Use this to your advantage. Being ghosts, by the way, they can move through each other.
• It's then hard to get down the bottom. You can spend 5 moves not eating and you'll need them all.
• You can't eat all of the bottom row at once; do some quickly, and the rest at the end. The letters you eat form a message, but the first part is ciphered.
