Will be finished/cleaned in Hammer when
A: it has finished being playtested and
B: when I learn to use Hammer.
Being a vanilla PeTI map, make sure to F6 when you deem it necessary.

As I said in my PM to you, this is a pretty good map. If you are going to finish in Hammer, some portal placement helpers would be nice, especially at the ends of the light bridges and on the floor under the laser in the second room.

Will do. Thanks again for testing my map.

I don't remembmer anything being that dangerous in your map, but it is a large map, so I would definitely recommend autosaves at the transitions between the rooms. Those and the placement helpers are fairly easy to do in Hammer; it might take an hour or two to figure out how to do this using the various tutorials available on the web. Also, double-check that there is no way for a player to get trapped. I didn't, but you never know what others might be tempted to do.

There are about two or three ways to get trapped that I know of, all of which would be easily fixed by the introduction of autosaves at key points.

Excellent map, I found your puzzles particularly challenging...took me longer than I thought it would. Even getting to the exit took a bit of thought. Well done.
Frequent use of F6 was very necessary. There were guide symbols, but probably could have been clearer - as I said I was surprised at the exit - forgot I had to get rid of the laser screen and couldn't find the triangle symbol for a while..

Enjoyed it! I look forward to the finished chamber!
