Yes, you can find these by clicking on the window of the shop to the right (outside of) the hotel.
One thing that I found really strange, finishing this game, was that the weirdo in the hotel ("mind always thinking... thinking about puzzles!") ended up playing no role whatsoever.... he doesn't even give you any more puzzles after the beginning. What's that all about? I expected to see a lot more of him!
