In which the effect of level five's blob-light is worked upon; a new lore-entry is written; a musical instrument receives label and description; additional responses are added to a puzzle; the "thoughts" system sees a minor extension; a convenience exit becomes a convenience teleportation; the manner of saving the selected resolution is altered; a crash in the prologue is fixed; a scaling bug is fixed; and the feature behind that scaling bug is reconsidered.
