Anyway, I do like the way that Deltarune's meta-level stuff is structured more. Namely that there IS a "meta-level," that You are unambiguously something separate from Kris, and that You and ______ exist on a different level where you're clearly beyond anything happening in the game itself.
Undertale's story is excellent but it could definitely be too heavy-handed and clunky with the way it mixed things.
