Ohhh this was already so fun just as a demo! I'm a big fan of including little puzzles and gameplay elements into VNs, and the metal gathering is a great excuse in-story to do just that. I had fun solving that first puzzle.
Nat and Izzy feel very real, especially Izzy's struggles with her personhood and her anger when she feels like her friend and everyone else are not listening to her. And the scene with Faerie feeling all that anger and speaking through Izzy felt unsettling.
Loved the art and the presentation too! Can't wait for the full release.
