Hey Scratchers! Check v2.2: http://scratch.mit.edu/projects/iuval/2014496 How to play: "Press the square buttons to flood fill the image with the color from the top left corner. Fill the entire image with the same color in twenty-five or fewer flood fills." v2.1 Now with 6 colors :D v2.0 Major script improvement! Same algorithm. This will be like the game Flood It!. Try it: http://floodit.appspot.com/ It needs a lot of work yet. The first thing would be to improve the speed. I have some ideas in mind. I try to use Back Tracking, in some way :D
