A strange little side quest
Between one round of New Bubble and the next, this is worth knowing: Arthur Wynne published a diamond-shaped 'Word-Cross' in the New York World on December 21, 1913; the name later shifted to 'Cross-Word' and then 'crossword'. It also connects to a different milestone: Doom changed game design and distribution in 1993 by separating its engine from content and spreading widely through shareware. That is the kind of background detail that makes another attempt at New Bubble feel a bit more connected to the history of play.
