Hello! Actually, I originally made it. To show/hide options just press SPACE. To change the color, drag the "COLOR" variable and notice that another variable called "Color" will change, that is what your color is. When the green TNT with a stick is pressed, you don't loose your work. To destroy your work, type 'y' in the prompt asking "Do you want to clear the canvas?" at the beginning of the project. To save your work just input 'n' and the TNT won't explode and won't destroy your work of course...
