I liked it, though the part in the dark was a bit difficult. It took me several tries to climb down the stairs, though I thought I had it down already. Just my take, but I wouldn't say it's an optimism simulator, so much as it's a great illustration of dialectical thinking -- just as the poem, in it's openness to interpretation -- which, I think, is the essence of dialectical perspective.
I don't know what dialectical thinking means, despite looking it up, but it sounds fancy and so I choose to be pleased; thank you! As for the part in the darkness, that's the one place where asking for a hint gives you something really useful -- a less invisible prey. :)
