No, but for what it's worth there seems to be more heads up on decisions that are blocked by a prior decision, so worst case you can save prior to key decisions, reload if you see one is required for a route, then just skip to where you need (skip is very fast, so it's not too much of a hassle thankfully). The dev also added hints for what decisions were key to which routes and the exact stat values needed for Keepers 1 after a while, so I expect that as the routes start to diverge more we'll get a guide. At the moment there seem to only be a handful of decisions that branch, and stat values haven't come into play much yet if you're worried about route lock-outs.
Edit: Shoutout to Lumari for both keeping the story held together and actually providing on a dearth of H-content. Humiliation/submissiveness is one of my strongest interests, and I adore that Rumi is presented as being equally willful and spirited as she is tempted. I don't normally think of foot worship as high on the pecking order, but you've somehow made it incredibly steamy since Keepers 1: I'm very excited to see where the sub route for Narumi goes, in addition to a return to being another certain catgirl's pet. Incredible work so far, Lumari!
