Quirky Self-Aware Ninja Game

Its just a game where you run around in a park as a Ninja chopping up bad dudes with a either a Katana or Shurikens. Inspired by that one scene in Ninja 3: The Domination where that ninja just kills everyone in a golf course for no apparent reason. Should work perfectly fine with a controller. If anything breaks (or if you want GTA but with ninjas) let me know!
