It’s done!
This morning, well before noon, I managed to start and complete the score attack mode. Once I got to the point of no return, I’ve completed the first Reflection as well as a bunch of earlier level with all the Idols activated. This was enough to get me above one million points and the last achievement was mine.
As amazing as this game is, it’s time for it to give up the place it’s holding on my hard drive for some other game. Other than a very likely future onset of nostalgia, there really is no reason for me to play it again any time soon. Amazing game, but I got all I could from it.
