Here it is, finally. And somehow it's even better than the file updates you posted now that it's in the portal. :D
The graphics were simply amazing. They slowed my comp down a bit, but it doesn't matter. That's why you put in a low/medium/high quality choice for us. Nice. :)
Sound is great. Nice choices of music. My favorite was # 2. It's very clear and fits well with the whole theme.
Since this is a tutorial, there's 100% chance of interactivity. Buttons all over the place. :O
The added humor made this tutorial far from boring. Nothing like those textbooks. Some sentences in there made me laugh for about 30 minutes. O_o No joke.
Overall, 10/10.
It's been fun being a part of this. :D
