Press the number key for a demo of each level. Level 1: Make the cat count by 5's up to 100 and then back down to 5. (5, 10, 15...) Level 2: Ask the user for a number to count TO. If the number is divisible by 5, count up to that number and then back down to 5. If the number isn't divisible by 5, tell the player, and give them a chance to enter another number. Level 3: Ask the user for a number to count BY. Then ask the user for a number to count TO. Check if the second number is divisible by the first. If not, tell the player to give a different number. Skip count up and back using the players input.
