Use the arrow keys or the scrollwheel/trackpad! :) As of v442 Flash won't capture the scrolling events so you'll need to go into fullscreen for the scrollwheel/trackpad to work properly, though this is planned to be fixed in the near future (see LLK/scratch-flash#977). See inside recommended. Feel free to use the two sprites in your own project without credit. You might need to change around the scripts slightly.. ;) I drew all the buttons and programmed all the scripts, except for as stated above.
