I think the implication that the lizard toy that was bringing the darkness - The sun coming closer, I have no idea of the person playing the Darkness did that as a deliberate Majora's Mask inversion or not - had been abandoned by the hero was interesting, as was the weird political machinations going on within the town that was at this point mostly populated by skeletons cursed with immortality - alongside a shrinking contingent of living people - but I think the scene we kept coming back to, cycle after cycle, with various lenses, sometimes from the perspective of the town, othertimes the lizard toy, othertimes the Hero, of children playing with the lizard toy before abandoning it because it was broken was my favourite part.
And ultimately informed the resolution - A scale the hero acquired from that scene being sewn back on to the lizard in a future cycle by a magical craftsman practicing forbidden magic, after it had broken off in the cycle that we were playing through when a prompt suggested it was time to bring it to an end, 39 prompts into the game across 4 cycles.
