This is a game were you just click the scratch cat and the scratch dog. They decrease in size when you click them. To switch between scratch cat and scratch dog (Yes, there's a scratch dog) just click “Switch”. But be careful not to touch the background, because it sends you to this screen that says “Oops! You touched the background, it's fine, everyone makes mistakes”, constantly plays the “Drip Drop” sound and ends the game. If you end up there you can restart by either clicking the “Try again?” button or clicking the green flag. If you take more than 1 minute to restart, you will unlock the secret part of the game.
