I'm glad you liked it. If you want a greater challenge try Seven Gates or Devil's Chamber. Those two are my best I think. But very challenging.

@jonatan.rydh thanks for getting back to me. I really like that, how to exit, initially seems impossible; then the only answer comes to you. Then it seems that getting to that point is impossible because you haven't got quite enough time, but then you realise you have, if you take into account flight time :)

@bullfrog yes that is the intended solution!

I came here from @SunnyOst’s Portal 2 Yellow Pages and I’m so please I did; great puzzle, definite thumbs up! I spent the first minute, or so, thinking “this is impossible!” Then how to exit dawned on me! It then took a little while to work out how to get to that point: intended solution ?

Wow! I loved that a lot; super understandable layout but a surprisingly long series of moves required. Thanks for making

I was worried not only about how to open the exit, but also how to reach it; when I finally succeeded in placing the cube at the correct spot, both of my worries were gone, woo-hoo! ^^
Nice chamber, I'm a little nervous about the other, harder ones. This already kept me busy for some time haha.

Maybe you or your brother should add "Gridlock" as well. I still have the .bsp, but it's a terrific map and it would be a shame if others weren't able to play it :)

Hehe, a couple of days ago I sent the .bsp which is still on my external drive, to a portal friend :)
This still remains an absolute favorite of mine. It's easy compared to your other maps, but nevertheless a real beauty :)
Thank you for posting (almost, "Beamtrap" and "Enigma" are missing) all of your maps here. I hope you continue to map because your hard puzzles have brought tremendous joy to me and a good friend, with whom I solved several of your maps together a long time ago.

Ever since TWP went down, nobody could find these anymore. Thanks man. People should really port their old maps to here.

Just can't see a solution - not so easy for me I guess. Need to get the wc out and into the button area - but can't figure out how to get the fizzler down and the funnel running at the same time as moving the wc.... good puzzle...
