Think of this as the core director for your progressive wave system.
It tracks zombie eliminations using a customized target counter, rewarding players with gold and XP for their kills.
It automatically advances the game to the next day when goals are met, initiating a safe grace period/pause timer between rounds.
It handles difficulty scaling by completely swapping out the active creature spawner groups every 10 levels.
It automatically revives any Down But Not Out (DBNO) players at the exact moment a day/wave is completed.
