This game is dripping with atmosphere and great ideas. Reminds me of "Scanner Sombre" with the camera mechanics. I mean that in the most complementary way possible, this is an awesome game and very impressive for your first Godot Wild Jam submission!
The jump scares were very effective! I'm not sure if you're preloading all of the 'enemies' when you enter a scene or if you are spawning them as the player hits specific triggers. But I would recommend preloading them into the scene and then activating them as the user hits those triggers. That way you can minimize performance hick-ups on web and make the jump scares really impactful
I sincerely hope you choose to pursue this project further. I'll be recommending this game to my friends to try out!
