Okay, thanks. I'd tried that before, but the bottles look like they line up as 3 8 9, or 4 9 0.
I managed to get to the end (I think). The painting puzzle was well done, with a lot of different clues to bring together.
Thanks for playing the game to the end, I thought the library puzzle was going to be too hard, but that doesn't seem to be the case. And the bright end sends you to the menu, the dark one restart the game.
