A Walk In The Park

I didn't understand this game. The prose was superb (some would say a lil' bit too much wandering on the poetic shore), the setting intriguing... but what was this about?

I mean: the goal is obvious but how does (Spoiler - click to show)selling narcos to a bird and offering the same to an old lady fits said goal? Most of the times I was strolling thru the park (uhm, yeah), doing strange things to NPCs or items for the sake of what?

Ah: and the provided walkthrough is broken. So I couldn't actually finish the game, properly. I suppose that's where all the things are explained. Although almost everything the walkthrough told me to do was unclued. It fits the protagonist, maybe... but certainly not me.
