Press the green flag to start the tutorial. ScratchCat will explain how to use blocks to make him move around the stage. The grid backdrop can be super useful to help you figure out the coordinate system. Press the space bar to move to the next explanation.
A future version of this tutorial will include a screenshot of the actual blocks used. I might also move the explanatory text to a list, and allow users to use the arrow keys to move forward and backwards through the explanations as well.
