Very interesting concept. I used the torches as breadcrumbs; not just lighting my way forward but also finding my way back.
Got a bit lost, wasn't entirely sure where to go. Often in game jams its unclear how much content there is. My suggesstiong would then be, at least for game jams, better hint at or outright say what to expect. Otherwise, if someone gets lost they might be left wandering if there is any more content to explore or not. Just a thought.
Overall, a cool game. I see you added several metroidvania-esk features. I like.
