Was just going to comment the same things, your reply covered me,
well done for making such a nice game in only 3 hours! That's is fantastic! I do not know how to do half the stuff you showed here! (could I ask if you have any tutorials to share? How did you made the lamps light up?)
Since I am also using Godot and new to this, I hope you dont mind me sharing this clip that helped me export my games in HTML5, so more people can play them instead of downloading them each time. Really helps me at jams.
hope it helps!
