Building a playable level for Swing Ball is really simple to do. The game loads its levels from regular BMP image files so all you need to do is create a new BMP image in this folder or copy one of the ones that are already here. As long as the image has a width and height that are both bellow 1000 then you can even make the image any size you want.

Each pixel in the image is a tile in the games map.

To place an empty tile just draw a white pixel (255 red, 255 green, 255 blue),
for a regular gray block use a black pixel (0,0,0),
for a green no swinging block usea green pixel (0,255,0),
for a red harmful block use a red pixel (255,0,0),
for one of the orbs that you can pick up for extra time use a yellow block (255,255,0),
for the levels finish use a orange pixel (255,128,0)
and to place where in the level you will start at use a pink pixel (255,0,255).
