Hi! this is my first project and I can't wait to hear what you think about it! anyway here are the controls that I feel are not self explanatory: change video transparency: click on the up or down arrow sprites make sure you press the green flag hold the palm of your hand up so that it is touching the pink ball. hold down the down arrow and start moving your hand to draw. The black dot is the one that actually draws. If you wish to just move the black dot without drawing, then hold down the up arrow and move your hand. I think that's all! constructive criticism welcome edit: space to clear :)
special thanks to my brain for being so awesome :p
