press the green flag TWICE and just watch until it brings you to the blank background. then start drawing! press the yellow circle with the green C to clear. otherwise, nothing works YET. once i get pen size and color working, this will be a real game! until then, enjoy this tutorial and pen away!
Hopefully more updates coming soon... Feel free to use this as a starter for any of you who want to remix and make it into a full sized game.
