Click the green flag to start the game. Press and hold h for as long as you want to show the high score, and release h to hide it. Listen to what Scratch Cat says as he will explain how to play the game. After the tutorial, the color will appear. v1: Added the red color, the play button, and the score simulator when started the game. I also added Scratch Cat's introduction. v1.1: Made it so the Score variable hid when the green flag is clicked and shown when message1 is broadcasted.
I couldn't create cloud variables, so enjoy :P....
