There are a few points where the translation doesn't quite do the job all the way, or which are otherwise worthy of note. I suggest reading these only after finishing reading the story itself.

• "Makai", for those not familiar with it, is what is sometimes translated as the "demon world", where the more fearsome demons and youkai live. Some of the early Touhou games take place there, as does the end of Undefined Fantastic Object.
• Love sign: "Agni Spark" seems to be a combination of Patchouli's spell card Fire sign: "Agni Shine" and Marisa's signature spell card Love sign: "Master Spark".
• Jaquet-Droz, first name Pierre, was an 18th century maker of watches and mechanical dolls of great skill. Alice probably thinks he is totally dreamy.
• Marisa's naming of Edward as "Captain Scarecrow" might partly be a reference to The Wizard of Oz, but is also a horrible and untranslatable pun: "Scarecrow" is "kakashi", but "kakashi" can also mean "lost", so she calls him a "kakashi-atama", either "scarecrow-head" or "lost head". Only the Oz reference is translatable, though, so I went with that.
• Marisa keeps making bad head puns. The "good head you've got there" line could also be read as "it's nice to have a head" in Japanese.

• When Edward refers to himself as Captain Scarecrow after entering Gensokyo, he also uses the specific vocabulary ZUN uses to describe his character's powers. This is completely lost in translation, as the Touhou Wiki game translations completely butchered these descriptions.

  For instance, ZUN does not describe Remilia as having "the power to manipulate fate", but instead uses the less specific description that she has having "power enough to manipulate fate". The pattern is exactly identical for every other character.

  Captain Scarecrow here uses the perhaps more manly "strength" rather than the usual "power", but otherwise follows the same pattern, perhaps an indication that he already has found his place in Gensokyo.

• The Japanese lyrics for A Pirate's Life For Me have a line in them about not forgetting, which is used here. Since no such phrasing is in the English lyrics, that allusion was lost.
