• The brushwork and detailing is very, very nice indeed - maximalist, but not too crazy, and pretty consistent throughout.
• Good use of inaccessible areas, they really help achieve that classic Half-Life illusion where places seem like a part of a bigger world.
• Sequences are very well executed (that scientist with the gun startled me as much as I startled him, lol), and the use of sentences is spot on.
• Most of the map is pretty silent, could use some more ambient noises (especially in larger areas)
• There aren't many enemies or weapons - if it were an intro map in a campaign that would be fine, but since it's a single level it feels a bit lacking.

• These types of light brushes are too solid-looking, a lower FX Amount (renderamt) value would make them more transparent.

• The pushable cart in the beginning can be used to climb past the crates blocking the corridor, but there is no way to get back from there.

Seems like an excellent place for a secret

• There's a null face in the room with the barney and scientist that is visible from the vent (if you look hard enough).

Between the table and the chair

Closer look

• The player can jump down this rusty shaft and get stuck.

Just make the lid solid

• I'd recommend placing the crowbar around here instead of later, to encourage the player to break this window.

I usually avoid breaking things with bullets

• This whole area down here is a bit too dark, the ladder is barely visible.

My gamma is 2.2, maybe that's why

• A foolish player can wedge himself between the large elevator and the light on the wall, a clip brush is needed here.

The cables got de-synced

1. the top trim under the hallway with the 69 above
2. the crate on the shelf near 1. is missing it's bottom
3. the top green metal crate is missing it's bottom

• a very high w_poly;
• the map needs additional optimization;
• it is advisable to make changes that improve gameplay;
• fix small shortcomings of texture.

THE WORST WAD IN EXISTENCE (THIS IS SERIOUS)
