I'm not usually a fan of them myself, unless they still tell you more about the story as a whole! There are exactly two potential dead ends, both right at the start, so it shouldn't require much replay even if you didn't save.
Bright Oak is not intended to require a guide, even once it's fully finished: my hope is that I've successfully telegraphed when options will result in a "bad ending" (such as they exist; there are precious few)-- and the vast majority of those bad endings are one-shot choices that can be reloaded without replaying the whole thing from scratch. ✨
