This is just a simple simulator. Just drag the pieces around to make a track in any fashion you choose. Then, place the marble at the beginning of the track and watch it roll down! You can press the C key to clear everything. There are 4 normal track pieces, 2 pinwheel track pieces, 2 curve track pieces, 1 switch track, 2 trampolines, and one container.
This is mine with an elevator you can also clear the elevator by pressing C as well
