I loved this bit of interactive fiction, though on my first playthrough, I had a bit of a flashback toward Majora's Mask when the first earthquake came.
The music was well chosen and set the mood perfectly, the timing for each character's movement was well done, and the subtle storytelling of each person as you follow them throughout this last day tells a much greater story that, quite frankly, I still am not sure if I get fully. (I did not understand the signifigance of the shovel, or why the drifter would be digging a hole at that last moment, unless certain thoughts hold true and he's digging a grave...)
Anyway, I loved it, enjoyed the neat Majora's Mask reference in the younger brother's story arc, and did not get bored with going through the day over and over again.
