My second favorite moment is at the end, when I'm back in my room and I'm revisiting the things that make me happy only now after going on that little journey I really FEEL that enjoyment, even though I'm saying the exact same things.
The only small thing I wish were slightly different is that instead of the music track being exactly the same at the beginning and at the end of the game, it would be only the simpler parts of the score that plays when you start in the room, so that when you're there the second time the music actually starts where the backup up choral track first starts and you experience the room again in that elevated way. It was the combo of revisiting the things in the room with that uplifting music behind it that just left me walking away super happy.
