This fantasy adventure is light on details -- the protagonist's brother feels like less of a family member and more of a placeholder to provide motivation for the journey.
I did appreciate the number of choices that Enveloping Darkness offers. The passages are short, and the reader is presented with something to do at the end of each one.
However, it would have been helpful if choices hinted at possible outcomes. I got killed early while trying to rescue an innocent victim, and at one point I spent two inexplicable months in a boat on the lake. It was a complete surprise when the story ended and I was praised for saving the realm.
Enveloping Darkness also includes several fantasy creatures that don’t feel connected to the narrative. Like the orcs used as generic outsiders: some are helpful, some are violent, and some are infested with parasitic brain worms. You could replace them with Canadians, and the narrative would be completely unchanged.
Overall, it could have used some developmental edits.
