It may be a tall order to expect someone to build it for you but if you start it as a project blog then you will probably find that people will throw in ideas and links to stuff to help you along the way.
As I mentioned in your other post, you perhaps need to start by uploading some pictures of the exact version of the game you are trying to replicate. It sounded as if you started to Build Lorrainbow's version but it was unclear as to how far you got or what modifications you made.
Linkable chapters would be a good idea and a text-based chapter list with short description of the content. That sounds useful.
Another huge factor for me is the chain of events (for the lack of a better term). Almost all videos start with an empty workbench and then the creator shows how everything is put together. If you are lucky there is a informative demonstration of the finished thing at the end. For me the ideal storybook would be to show the result first and then spend as many hours as you want showing how it came to life. I don't care. After reading a teaser article about the thing I want to see it in action, that is what was teased. The build process is secondary and mostly for people how do something similar. Did I say that I hate time-laps sequences of things get screwed/glued/cut. You cannot see anything useful.
