This was genuinely scary and haunting! The audio modulation and usage of vfx and different sprites was so on point, I greatly enjoyed this!
As for criticism, I would've preferred if answer buttons appeared after the text finished, and maybe you can look more into UI theming in godot to avoid small things like the focus box briefly appearing after you press down on a button before you release.
But those are small points of note from a fellow Godot developer, from a game experience standpoint this was fantastic!! good job :3
