Average, with promise
Graphics, 4; The box itself was neato, and the bouncy effect was cool. The rest of the tutorial was lacking. Were it me, I would make my arrows and text coordinate with the actual box by making them shiny and kind of rounded. It wasn't much of a sight for sore eyes.
Style, 5; A bit plain and boring, but I give it an average score because you kept it clean and clear.
Sound, 3; The song was overpowering. It might work better if you used it only on the screen with the completed box. For the rest, maybe some lighter background noise.
Interactivity, 3; I had hoped that the actionscript text would be copyable. It would have saved time and been less daunting for a beginner.
Overall, 5; I voted 2. It's a neat tutorial and I sincerely hope you work on it some more. I know I'll be making hundreds of these when I'm bored from now on! ^_^
