The face riddle part 2

[remanufactory]

There are three additional conversation you can do with the face. Note that below is not the original english language, so your version may vary.

I haven't checked them all, only the one you get in change for the coins.
Here, she mentions three secrets:
- you can find a secret kingdom if you start to breathe freely
- you can find a secret door if you look for it where you can see more clearly
- you can find a birthday present in the most beautiful place.
- if you put the pieces together, a marvellous secret will be revealed.

What are your ideas?

The first one can refer to the secret tower. You can find it when you flee your cave for the smelly sulfur fire. The shade will go to the tower, and will stop saying "now I can breathe freely".

The second one obviously refers to the secret door connected to the stork key in the tower, but what does "where you can see more clearly" refer to?

The third one I assume refers to the crystal cave lake. Will you find your birthday present there?

What else you got?

[Anteroinen]

Pretty sure "where you can see more clearly" refers to the map room doing The Thing.

The first one can also be done by listening carefully to where you're walking on in the darkness with a good pair of earphones/headphones. Once you hear your Shade stepping on muddy surfaces, point your mouse cursor to the top right and keep going until you reach the secret tower

The second one: go to the map area, investigate the map, look for a closed wooden door around the map, go to that location at XXX days 00 hours 00 days 00 seconds, open the door with the key from the secret tower, take everything, wait for another 24 hours for the door to open again

You got it right for the third one

The marvelous secret (DO NOT READ IF YOU HAVEN"T GOT ALL THE SINGING CRYSTALS YET) put all the singing crystals (one from the secret tower, one from the secret door, one from the crystal cave on your birthday) together and you get the fifth ending which is a cute reference to Silent Hill's UFO and Dog Ending
