The Curious Correspondence Club: Chapter IV: The Moonlight Escapade

Difficult but delightful puzzles.  Two points of flawed game design: 1) a transparency was marked "A", without a period afterward to indicate which way it should be facing; it was very easy to implement the transparency correctly but backward, and thus get usable answers that were incorrect.  2) The term "descending" was used to clue a puzzle, with multiple ways of interpreting what "descending" meant (the order in which to assemble something, top down? the order in which to number elements?)  Again, each way of interpreting the meaning yielded a usable answer, with no real way of telling which way was correct.
