I'm playing custom maps and record my first time of playing them. So the run is not perfect and may not use only intended ways, but maybe it can let you see how other people may understand the map or you could just enjoy someone playing this map for entertainment.
Anyways, here is the recording:

You're definitely improving. ET3 is even better than ET2, maybe not so much in looks but definitely as a puzzle.

Minor appearance problem; the source of the excursion funnel is just a panel, without the internal pieces. Works fine, but looks wrong.

I loved your "impossible geometry" due to world portals. When I went to the white gel button I thought I was losing my mind!

Because of the direction you have to face to set portals for the final fling, you don't get to see the fling itself. You could turn the right way, but by the time you figure out you needed to, you've missed it, and you can't go back and do it again.

This is a solid 4/5 from me. With better attention to detail and a little less running around, it could have been a 5.

It took a while, but I have another update for this map

I'm stuck...

I used the funnel to get right to the top, then got the cube and put it in the receiver, then dropped back down to the first room, and now the funnel is off and I don't seem to be able to get out? There's just the laser and no way to reflect or portal it?

did you use the faith plate while dropping down?

This is easily your best solo map so far. I like "Inception" theme that forces the player to return to previous areas to use new elements. I was going to say that the only thing I didn't like was the funnel climb, but then I realised reading above that that is not an intended technique. I should have shot some blue gel into the room to jump into the funnel. In any case, you can actually funnel climb in that spot, though it's incredibly hard and frustrating Expletives were used in the solving of that part! Not sure if that is an exploit or not.

One quick question. I tested the mat fullbright_1 command that you had just reminded me of on this map. It works great all in all, but it made the gels disappear. They still worked, you just couldn't see them anymore. Is that normal?

That's an unfortunate side-effect of mat_fullbright =(
This map should have enough lighting to play without mat_fullbright though

Glad you liked the map

No worries. I didn't need it for this map; I was just testing.
