This is legitimately really good! It's definitely the type of game I would just have open in my browser and dink around for the vibes. The art is really nice!
I really love the banjo song, unfortunately it seems like after you click on it, you can no longer interact with other things, though.
I also think turning on the light is really fun, I would make the glow around it stepped, or pixelly in some way. You could use a sprite with transparency. It's just almost the only thing that isn't pixel art, but it totally could be to harmonize with the other art. that's just my 2 cents though.
Also impressed with the inventory, it took me aaaaaaages to get an inventory working with Godot.I'll keep checking back for updates
