Oh, definitely that would work nicely, plus it would add another element of "resource management", so to speak, by giving the player limited time to explore their current surroundings. On top of that, you could possibly have the creatures attracted to the braziers/torches while they are producing light,making the situation feeling even more urgent, but I'm not sure that would be appropriate story-wise, since I know little about the Jikininki folklore and if they hate light and/or fire.
