Nice work, this is a pretty complex setup for the story and there's a lot of interesting passages. I like the beginning, how you have a couple of passages of intro before the first choice. The management of different choices at various parts of the story is well done for the most part. There are a couple of confusing sections, for example, in one ending I'm stuck in a loop where I can click on "mountain-return vine" and then that passage has a link to "go back" to the previous passage, so it seems like an endless loop. Having some start over links, or returning to a previous choice might make this a bit more clear. There is another passage where numbered options are shown, but it seems like in some cases some options are not available. This is a nice setup, but it makes the numbering confusing, if you just see 1. and 3. I would just have the options listed without numbers.
The drawings are very nice, but I don't see any image citations. The images should have a citation for a public domain license, or other licensing information, or if they are your drawings you can indicate that as well.
