So, hypothesis time: the island's stuck in a big loop of some kind. The reason for my theory, is that nothing seems delapidated or worn down, as if time hadn't affected it, as well as the more symbolic imagery of the whirlpool of time beneath. If the river of time is a whirlpool, then it's travelling round and round on itself, like a circle, forever repeating. Whether this loop is infinite or has an eventual endpoint/'out' is yet to be seen, but considering the water eventually drops into an abyss, the way out is likely dropping off the edge, and my guess for who the *footsteps* belong to, is that they're Sunny's own footsteps, seeing as they were described as smaller-sized. :)
Cycles and circles and I think a few of us are on the same wavelength here 💫 I was thinking the whole island consists of different loops and time works or runs differently in each. Or jump and begin again 😳😂🤣 Or both 🙃 I seen a comment about survival, a somewhat willing loop just to survive perhaps 🤔
