We need to:

• untangle the scenes (circular dependencies are a nighmare)
• add flushPalsWithFade to natu
• remove some of the last minute hacks (especially game-over handling)
• make a general system for popping up label sprites, rather than handling it all in the board.
• implement a "task" system so you can fire & forget some long-running logic rather than adding more timers to the board.
