Well, now that I?ve managed to extract my foot from my mouth?

This shot is pretty representative of the general texturing/architecture/lighting level of this map. Suffice it to say it isn?t very high.

This is a nice touch as far as it goes. It explains where you came from, which is something that is often overlooked.

I don?t appreciate being trapped. If you are going to setup things like this, just kill the player. Also, these halls are WAY too narrow. they are simply irritating to navigate.

Um.. Yeah. I?m inside a cramped little cylinder with no lights in it, yet there is light?

This is the best constructed are I found, but you should note that you have too many env_shooters here. My HL crashed twice when walls collapsed.

Flat lighting, simple architecture, lighting errors on the pillars, and boring texturing all let this are down.

The stained glass window is a very nice touch.
Your little death messages are kind of amusing, but it does get kind of old to die with no warning.

It?s best not to expose unlighted edges.

The sword is kind cool, but it would be cooler if it didn?t entirely replace the crowbar. Now I?m going to have to delete this model to get the crowbar back. Ditto for the bible/satchels.
It?s an interesting concept. I think it would be very cool to see a good first-person dungeon crawl in HL, but I?m sorry to say I can?t think of much else positive to say. You obviously have some significant technical mastery of HL since you were able to put together some relatively complex entity setups, but the visual execution was, to put it nicely, somewhat less than desirable. Texture misalignments are rampant, the architecture is rudimentary, and the lighting gives me seizures. In far as game play goes, I can?t say much there that is good ther either. It is far too easy to get stuck, traps that kill with no warning are irritating and everywhere, and corridors are so cramped as to make navigation difficult. If there is a redeeming factor to this whole effort it is the weapon replacements, but as I mentioned, even those are a source of irritation because they replace existing items. I think if you want to do something like that you really need your own mod folder.
I say take this idea and run with it. This could be allot of fun if you were to spend about 500 times more effort on it next time.
