Great update!

I had to update for another bypass that mood3rd found so I have also made this ledge accessible with an angle panel and an escape route, to provide more interest perhaps.

Very enterprising! But I see why you would not then be able to escape after using that method. I will think about it :)

Maybe a litte demo ,

Actually I think there would have to be portals already in the main room, one of which you could portal back to from there. Might be interesting to look ahead from there, I like maps which are not just linear, gives a better sense of orientation...

That was my point: from there, I can not aim at another white tile to portal to...unless I'm missing something. You could take out the last part of glass on the far right and replace it by grating, so we could go there, have a look down the floor glass and come back. Of course, your map, your choice!

I thought it would do no harm to leave it just in case somebody found a way to get in there. I always do my best not to trap anyone, the greatest portal sin :)
