There are 5 premade projects, you can use the tools on the bottom. For the wall tool and the eraser you have to press "c" to make them go away if they dont already, the wall tool is supposed to go away by itself but the eraser you have to press "c", if the wall tool does not go away, just press "c". Hint: You have to download this for it to work, otherwise it will just be stupid. Hint2: The roller coaster only rides on the black line, the other colors are for decoration.
