So I'm in the cave system in chapter 4, and I'm not sure if this is a puzzle I need to solve, or if the failing path just isn't implemented yet, or if the current demo is actually just over. This demo is really amazing, by the way! That's why I don't wanna just leave it without realizing there is more available, haha :)

Hi there, yes, if you got a message saying “this is end of the public demo,” it’s indeed over! The demo ends at that point in Chapter 4. :) I’m so glad you enjoyed it! Thanks for your kind words, and there’s always more over on the Patreon/alpha build version, as well!
