Very cool idea. I think I would have climatied better to the idea if I had a starting area with lantern refills before delving into an area with no refills.
Some nice traps to reinforce that you need light, fell into a tar pit (I think) when I slacked off, pretty clever.
Health/ Stamina bars don't seem to refill after hitting zero, thought I had run out of stamina permanently before running showed that it was actually full.
Played with Hue lights for maximum light immersion.
