Photo Dojo

In short, the Killer App of DSiWare. It allows you to take photos of yourself and you become a character in a fighting game.

This game provides examples of:
 * Crossover: You can put anyone in the game if you have pictures of them. Such as Naruto, Edward Elric or Weavile.
 * It's very easy to put the character in if it's a ragdoll in Garrys Mod. Heavy anyone?
 * First-Person Snapshooter: You become one when you play.
 * Killer App: To DSiWare. And it's free for its first month of release.
 * Level Editor: You make the backgrounds as well.
 * Narm: Your recordings tend to turn into this.
 * So Cool Its Awesome: Having your likeness in the game.
