Not really suited for flash.
Alright, I'll start off with saying that it was a pretty good tutorial. But this simply isn't a flash. Not for NewGrounds, anyway. This would be better suited for your own website or something, or maybe uploading it to any other site that doesn't go by a scoring system that compares this to other flashes with effort put into them. I'm not saying you're lazy, I mean this is all that was required, but it's not like you lost sleep over the matter. =/
I'm not entirely sure where I'm going with this. It's hard to critique something like this. I can't offer room for improvement because frankly, it's a good tutorial, but it's better suited as a book or something... But now I'm just repeating myself, so I suppose I'll leave you with that and have a happy new year.
