For those too lazy to play through the map for all 4 endings, here you go:

Start:

Eye: Why are you here?

Option 1: I have a question.
Option 2: I'm lost. Help me.

For option 1:

E: I'm listening.

Option 11: Why am I alive?
Option 12: Am I alone in this world?

For option 11:

E: To learn pain.

Option 111: I don't want to learn pain.
Option 112: I'm not afraid of bleeding.

For option 111:

E: You have to.
E: That's how life works.
E: You get used to it.
E: So you must deal with it.
End.

For option 112:

E: Good.
E: This is just the beginning.
E: Be strong.
E: I'll keep an eye on you.
End.

For option 12:

E: Always have been.
E: But if you believe in me...
E: I'll always be here for you.
E: But for now, rest.
End.

For option 2:

E: This world is lost, not you.
E: Don't be discouraged.
E: You'll find your place in time.
E: I will guide you there.
End.

I normally never comment on maps, but I should say I think this map is very good!!

That inner reflection in the little TV was very cool. Interesting interaction.
But I have to ask, "Were you tortured by a chair and a screw driver as a small child?"

you're welcome

This map keep me strong, thank you for this masterpiece.

First time I have seen an interactive element in portal.

"This is Just the Beginning ... I'll Keep an eye on you." most interesting outcome out of all the options.
