Use WASD and space to control the scratch cat. Set fly to 1 to enable flying. Use Up and Down Arrow key to fly.
This project allows you to move along the x, y and z axis in a 3D space. If you want to be able to move in 3 dimensions in your own project, copy the custom block into your own project, and you're ready to have a sprite moving in a 3 dimensional plane. Remember to give me credit, if you use this =), and shoot me a message if you used it for something cool :D
