I'm a fan of 'two-world' type games, and this one fits the bill.
This game starts out with you in a sort of Plato's Cave. Soon you find yourself in Faerethia, and then there is a flashback to (Spoiler - click to show)the real world.
While there is an overarching story (one that has been done by several people, even up to Dr. Who and MLP fan fiction), the real thrust of this IFComp entry is its philosophy. It tries to tackle identity and the idea of continuity of self.
Does it work? It might have been hard once to imagine getting any kind of deep discussion out of interactive fiction games, but there's been quite a lot of work in IF that tackles big issues in a professional and educational way (like the excellent game Hana Feels).
Does this game reach that level? I'm not really sure, but it has a lot of polish, and it's not quite so heavy-handed as many other 'deep' games. I felt my playtime was well-spent.
