WASD to move. You can put this in any game you want. Be sure to use credit first though. I recommend using 45 ghost effect, and trails amount 0. Hover the top and bottom with your mouse. The flaw of this is that the background and the cat is low quality because of the way the motion blur works.
Sky 3 from random image I found on Google. And sky 1 and 2 are from scratch.
