The writing is lovely, and the side light paying out in three steps the longer you stand there is a great hook.
One thing about the budget, though. The page says reading the light "costs flame you needed for the walk", but the numbers leave room for all of it. Walking the whole road takes about 52.6 s, all three stages take 20 s standing in the zone, and holding the torch out costs 12. That's 84.6 of 100, so you can see everything, give the light, and still reach the gate with about 15 s left.
I checked it with real keys on the web build: held Space to mark 56, stood until all three side lines were showing (20.5 s), held the torch out, then walked to the end. The card said "flame left 14.8s", road walked 100 of 100, 0 console errors. So the only way to miss the gate is to stand around somewhere else. It also means the "a gate you can feel and not read" line (it needs under 12 s at the gate) misses even the patient run by about 3 s.
If you want the choice to cost something, a flame of about 80 s, or a bigger GIVE_COST, would mean seeing it all through costs you the gate.
