This is very neat! Piecing together a story based on the answers is more difficult than it may first appear, as hints from other branches effect each other in unexpected ways. Ultimately it is a bit of a niche experience. If set up as some sort of multiplayer game, akin to some of Jackbox's games, it could be a very fun social experience where one player writes a story based on predetermined branching choices, others play it and then you create the next chapter starting from where the players ended up on the branches... Neat proof of concept and very creative!
