This project is also found on my real account, but this is an improved engine of it. Use the arrow keys to move the ball and it will scroll, but use the WASD keys and the camera moves in stead! Also, press space to change the camera from Scrolling mode, Locked mode, and Centered mode. This would be handy in a scrolling game so you can see what's ahead of you a bit more than usual. It's also just a nice feature to make your project look more professional.
