* BigLippedAlligatorMoment: The bizarre insect device Rain's strapped into near the start of ''Retro Helix''. Its purpose isn't explained, she's freed from it in seconds, it makes little sense, and it's never mentioned again.
* LesYay: Hana and Rain again, in ''Retro Helix''. The reaction to their relationship at the time was pretty hilarious. While the game and its marketing were anything but coy about it, with a Europe-only two-page magazine ad featuring the two of them in their underwear, several reviewers and writers at the time tried to act as if it was simple subtext. This was a handy way of being able to figure out how far they'd been able to get, as Hana's love for Rain is a major factor in the game's latter half.
