NinjaCat Training is a survivor video game made on HTML5 Canvas and Javascript. The objetive of the game is to avoid all the obstacles such as Shuriken Waves and lava floor, jumping through the platforms to survive the hard training and become a trully IronNinja.
The complicate part of the game was to achieve fluid moves, especially when NinjaCat Jumps. Also get great and reals collisions. The get his I was working on a main constructor function that allow me to create diffeent kind of collisions and defining the behaviour of two elements when they're collisioning.
