Thanks for the feedback! It seems I may need to add a similar flash effect for the bulbs as well. If you talk to an NPC while an important item is nearby, they'll clue you in on that. The monster is also supposed to despawn if you fix the lights so that's weird...
I want to find a balance of feeling lost but also sometimes you need to know where you're going. In future I'll consider adding a map item so you can see where you are, unless this is fixed with procedural generation.
Thanks for playing!
