The dot follows yr cursor. If u click down then the dot draws. To choose a color press "Space" and click. If u don't then u will accidently draw when u click down for the colors. Press "c" to clear yr drawing. Press "v" to hide the colors. Press "b" to show the colors again. HAVE FUN! :D
I got my ideas from the website weavesilk.com. Its a GREAT site and pretty fun. I give credit to all who favorite or like this project. SCRATCH ON! (I am trying to not type weird and type weird things. U will notice that if u look at my other projects.)
