I'm afraid I might have tried to be slightly too clever in the early game and got completely stuck, but wanted to check here before deleting my save. I'm at the room in the lava zone where there's a door surrounded on all sides by lava. and what appears to be some other type of door to the left that is inaccesible because of lava. You can find the other side of the first door in the previous room, but i don't see the purpose of that since you are just surrounded by lava. I've tried backtracking but it doesn't seem like I can progress from the area two rooms back where everything is in silhouette. I'm afraid there's some song I missed; right now I only have the one that shows your location pin on the world map, and the one that creates a yellow halo around your character (I'm not sure what this is even for). Am I missing something? Is there a way to get out of this corner I've backed myself into?
