Really nice art style, although the contrast makes it kinda hard to see the character in some points. I see you're a fellow Godot dev, always nice to see! Loved the story and dialogs. Is the endless loop conversation normal at the end?

Art could be great, but there's little contrast in the colours that they merge together and that holds it back.

Couldn't tell if the key was there or not. If not, then the game is basically a waste of time for a person to be looking for a key that doesn't exist. If the key does exist however, it is near impossible to find as I scoured the whole area.
