Really liked your entry, and it was specially beautiful since you made it in Godot (I love Godot hehe)! 😀
The graphics look very good, I see you have applied normal maps a lot of things to make the environment look good, perfectly done! I specially love the first segment where there's a lot of fog. you should consider keeping the fog in the game, it makes it look better and more "mystical"! 😋
Since you are using Godot, I recommend you to go into this page. There you will find many shaders that you can use in your 2D and 3D projects! I would advise that you used this shader to highlight the things that you can interact with!
The controls are a little rough. I guess that you wanted to give the player a "rusty robot" feel, but turning with A/D seems like an ancient mechanic when there were no other ways to rotate a character. I would advise to change the controls to use KB+M instead of only keys to move and use the camera. Instead, you can make the player feel like a robot with the animations and sounds of the character.
I also found a bug, there are some walls that seem to be missing collision, and I ended up falling to the void!
Other than that, very good entry! Excellent work! 😊
