Fun little game!
- Having the overlay remind the player to press the Next Level button over and over during the last minute is pretty distracting/annoying if the player doesn't have the points to actually press it. Maybe add "and (currentPoints >= newLevelCost) to the overlay's trigger?
- (Sometimes) If the player replaces a bumper with a new one before the first bumper of the level has been 'organically' removed via the dropped balls, the old bumper is not added to the player's inventory.
