First of all, I love the story. I like the backtracking and the emotion-eating beings (they gave off a danger vibe) The atmosphere is good although the tilesets could actually use some work. You know your game design well, especially the part where you muted the music because something bad is gonna happen. The game is good and the story is amazing along with the mix of future and magic, good job!
I also use godot on my game so I noticed some things, you forgot to turn off the "export with debug" on. The robot double jump can be fixed (maybe it's intended?) if you parent the sprite to a node2d, this way you can just set the node2d parent scale.x to -1 or 1.
