Kail sample sprites

Hi! Just some points I'd do to improve on this:

- First redo the running animation. Take a good look at what the legs are really doing, but also note how the upper body is working too. For example, in a proper running motion, the body leaves the ground. Decide on whether you want a running or a walking animation.

- Weapon swings need to be larger. If you want to make a more natural, realistic animation, you need to take a look at different stages in a swing, like lunge, accelerating the blade and swinging out after the hit/non-hit.

- Next I would maybe add a landing animation

Have fun working on this!
