I've just read through it. It makes sense to me only as I have 3D knowledge.
I think I could probably follow it to make the stairs.
I think your problem is you need to explain things a bit more.
you have in there *DON'T USE TRIANGLES* why not? what happens if you do?
You need to explain keypress's a bit more..
I think people find them too technical because you don't give enough detail on each part.. why you do it this way not another, or what happens if you do such and such instead.
I'd also run a spellcheck and take out some of the slang words.
Pictures are a good inclusion, much better than the draft .doc file you had to start. A picture says a thousand words.
Just fill it out. Give it some character and give some more info.
Than see how it looks.
