The ambience and the art both are really neat ! I've got a few nitpicks though!
- The stairs that go down have the same graphics as the stairs that go up? That feels pretty unintuitive to me to be completely honest x)

- The sound that plays when only 10 seconds remain before the lantern's fuel runs out is ANNOYING in it's current state !
It plays very early, lasts for a ton of time and doesn't stop immediately when i pick up fuel !
I feel as if the tension it gives would be greatly enhanced if it played closer to the end of the timer (~5-7 seconds left) and if the sound stopped when picking up more fuel ! (since the stress of it running out isn't a problem anymore when i pick up said fuel)
- After picking up the 3 map fragments, the zoom to the basement left me slightly confused as to where to exactly go to reach it, i managed to find the door by walking around but i don't think there were any indicators of it suddenly appearing right after the fragments were picked up? (i guess the cutscene IMPLIED something changed but it wasn't really clear to me)
Apart from those nitpicks i listed i liked it ! Spooky games are nice ^v^
Everyone who worked on that game, good work !
