Dang, creative idea. It took me awhile to figure out how the fires correlated to time (tbh, i'm still not sure I totally understand it), but I think you presented it well enough. I will say I struggled a bit trying to figure out where to go, and that coupled with the mystery of the mechanic itself made the first several minutes somewhat of a trial-and-error mess for me. I think if you included some subtle directional elements in the background or the foreground, it might help direct players and minimize that feeling of being lost (unless that's exactly the feeling ur intending, or maybe you did and Im just blind). I also don't know if the ambient cave noise is doing the game justice, and I might've been more properly engaged with a more suitable music track, but perhaps that's just artistic preference. Overall, this game reminds me of Kingdom Two Crowns in how the primary mechanics of the game are something that the player has to learn through observation, and that's a great thing.
