Hi there,
Thanks for playing! As for the doors, no there is not a way to unlock them. Thinking of it, it would actually be cool if there was some puzzle with the doors and lights.
The lights at the end are actually not unlit but that‘s hard to see because it‘s so bright. They are there to guide players to the edge, but I realize now that they might cause players to think there‘s more to them, because they look unlit.
Hope that clears things up! :)
