Can portals be made on the glass?

Nope.

Fuck. Okay. So stepping on the button makes the door open, but she can't get through the door on the button. What's up with that cube dropper?

As soon as she gets close enough to the pit it drops a cube!

Too deep to jump, but the floor looks portal-able so if she puts one underneath the cube-

—it comes out of the orange end!

Grab it in the field and drop it on the button.

The door opens! There is an Emancipation Grid on the other side.

Still doesn't like those things. She darts through.

Her portal gun vibrates a bit but nothing other than that happens.

On the other side there is a short corridor and a chamber with two large red buttons connected to the exit door, two elevated platforms (one of which is next to a wall with an orange portal end and the other of which has a cube on it), and a pit with a cube near the back.

Let's see... both cubes need to get to the main level, so... Easiest to coordinate from the fixed point. Get up there first, portal to the other high cube, grab it and toss it down. Then get the one in the pit, then both of them go on buttons.

This is so fucking pointless.

"Great work! Because this message is prerecorded, any observations related to your performance are speculation on our part. Please disregard any undeserved compliments."

The room on the other side of the door (and Emancipation Grid) has a glass ceiling through which she can see a portalable ceiling farther up and an orange portal end appear.

So- portal down here and step through.

The glass cracks on impact, and the window breaks, hanging onto the upper level by only one edge.

"I hate this place."

The place is indifferent to her hatred.

Up ahead the way to the door is blocked but it's trivial to walk around the blockage through a side room that probably should not be accessible. There are metal stairs in it.

Maybe there's a way out. What's up the stairs?

Something like an office or observation room with a weird crayon drawing on the wall. Not, at any rate, an exit.

Bleh. Fine. Back down.

And down the elevator and "If the Enrichment Center is currently being bombarded with fireballs, meteorites, or other objects from space, please avoid unsheltered testing areas wherever a lack of shelter from space-debris does not appear to be a deliberate part of the test."

Who the fuck recorded this shit?

Whoever even knows.

The next chamber has a sort of metal grid blocking the way, but she can see an orange portal end on the other side.

But the floor is portal-able, so.
