Shoot the wolves with apples (Space bar). The cat will give you an extra life. Hold Space and click the flag a few times to turn on Hard Mode. You'll know when the music changes. Hard Mode is hard! Click it again a few times to change back.
This was just an old coding assignment I decided to brush up on. Update log: 28 Feb 2018: TWO NEW WOLF PELTS! Parrot, cat, and wolves are smaller! Feather effect looks less odd :) Apples and turning are FASTER! 17 Oct 2016: Added rainbow wolf, which acts as something of a boss. You'll lose three of your lives if it touches you, so get it quick! They appear every 50 to 100 seconds (25 to 50 in Hard Mode). 31 Mar 2016: Release.
