Ball kick thing

Trying out Unity again. This time, I'm properly learning that engine here.

So here is the first thing I went out to make. Made it in 3 days or so. I'm won't promise this will be made for a full game.

You are the white ball. Pressing any direction key will kick you to his direction.
You can kick yourself in mid-air up to 2 times. The ball will change color if you can't no longer kick it.
You have to wait a bit to kick the ball again. Again, the ball will change color for it.
Press R to respawn back to the starting position.
