Completed it. Was really fun, thank you!

I wasn't sure how to chain function calls so had to look that up to implement movei, but apart from that was fairly straightforward (it's (do (<func1>) (<func2>) ...)).

My UI was pretty simple and ended up being

    (defn looki [] (display-html (look-html (look))))
    (defn movei [dir] (do (move dir) (looki)))
    (looki)
    (movei :south)
    (movei :east)
    (movei :north)
    (movei :south)
    (movei :west)
    (unlock-function :spoiler)
    (stack)
    (push :picture)
    (push :spoilers)
    (peek)
    (pop)
    (reset)

I got a bit stuck.

(I got the 5 items. Somehow lost :key-code. I think I inadvertently duplicated :close-paren and :unlock-function, though I have no idea how.

In :utility-room, the "bookcas " is missing an e.

When the mouse is over one of those inline-eval boxes, "scroll up" works, "scroll down" does not.

edit: oh, I was trying to play the whole game before the rest of the article too … so that was probably harder than it needed to be ^_^

edit: (pop) seems to be what screws up my inventory, dropping multiple items from the stack, but if :a :b are dropped, they end up as like :b :b ?

edit: I think I beat it? I got to exit-to-freedom, which I'm assuming is the end.

I believe you may be able to do it with a 3rd party keyboard app. I was able to use one for my Android phone, just unsure what's available for iOS.
