Much harder than the last one. There are a couple flaws, namely that the antline doesn’t light up when pressing the button to turn on the gel, and the exit portion looks a little “blocky” and undetailed for my taste. Still a great chamber and series, all in all.

Not so easy this one..... but clever puzzle. Znx for this serie, you should make more! The puzzles are a bit devious, like the ones of Mevious....

Took some time, but eventually I found the solution that wasn't timing critical. Nice headscratcher, thumbs up.

i did it a different and much easier way than bullfrog. i did coat the gel button room floor with gel. i placed the cube under the funnel,i sent myself upto the ceiling over the funnel hit a portal on the floor in the button room. dropped into the funnel ,so now i took the funnel up to the ceiling in the button room. then i usedthe funnel under the cube to take it into the original funnel [so now i am bouncing. then i put a portal on the surface to take the cube to the button on the wall.then i hit a portal on the angeled surface another one on the floor and away i go. worked great. i had fun with this map. [spoiler]

that was really fun! i didnt have any problem once i figured out what to do.

Ridiculously buggy. Also, the timing required for the solution here isn't very fun.

I was about to say that, out of the 5 maps, the solution to this one, with its tricky timing, was a bit disappointing i.e. funnel, gel blob, self AND CUBE in gel button room, cube on floor, funnel self to ceiling above gel blob on floor, funnel cube to ceiling while you bounce, then shoot portal on far wall so cube flings through and reshoot funnel to catch it to turn off fizzler – which took many attempts to get right! – shoot portal in angled panel, other portal under self and fling to exit. But I saw your reply to @I before A except after K and watched the video! Good puzzle when done the way it’s meant to be done, pretty rubbish if you’re stupid enough to try and do it the way I did XD, thumbs up and thanks for the series.

Great job. Toughest maps I have played. Needed YouTube walkthrough for 4 out of 5 of the Compromise maps. Really helped me sharpen my critical thinking skills. Thank you very much.

Nice set of maps in this collection of 5.

I first used the up-the-tube exploit to get on the roof but that seemed too easy. Then I went back and did it the intended way.

All the compromise maps are designed well, easy to medium difficulty but very enjoyable. Thanks for alle the maps. Godd job

Very Enjoyable! Thanks.

Fun! The intented solution is a already a lot of fun! But, the bug, which made me flyyyy around the chamber as if it was underwater was even better... :-D

Several "aha!" moments in this one: 1) How to get a portal into the button room from the outside. 2) How to get gel into the places where they are needed. 3) The final solution sequence. I'm sorry to reach the end of this series.

This one was really neat. It is possible to escape through the top if you're clever, but there's nothing map-breaking you can do out there. The intended solution was really satisfying, but reachable in a reasonable amount of time.

Read my profile before reading the rest of my comment!

This reminds me of Mevious's understanding of blue gel, specifically "Height". Well done.

What a great collection! Really enjoyed these. :)

This whole series has been astounding.

Brilliant puzzle. Funny how the only maps in the series I have solved so far are the first one and this one. These maps are really well done, I must say.

I'm really bad at these! But good job!

Excellent!

awesome! the whole 5 map test track! love it!

Was what I did the intended method? Use the funnel to hoist myself in the portable floor behind the fizzler, which is covered in blue gel. The cube is in that area too. Then hoist the cube while I keep the momentum by bouncing. Then as I come down fling the cube and as I go up quickly replace the portal the cube fell through with the funnel to press it against the button. Then when I bounce back up portal the angled panel and beneath my feet to fly to the exit.

Brilliant maps with good amount of difficulty.

DED before TAR except after RE.

This one was a lot of fun to solve. I've never done a test that involved that much bouncing :)
Maybe you could add some space between the grating and the floor to prevent the cube from getting stuck in there. 128 Hammer units should do it.

unintended solution: paint the cube make it stand up angled towards the exit make the funnel go up right behind it and jump onto the cube bounce to the exit

Excellent puzzle, thumbs up. The architecture is not as interesting as some other parts of this series, though.

When the frankencube is dispensed and, occasionally, at other times, I hear the "Oh, fiddlesticks..." that means that a sound file called for by the map is not installed. This happens on all Parts that I've played so far. Any idea why that might be?

There's a bug where the cube get's stuck in the grating when you don't shoot the portal in front of the button intime, so I had to get another cube.

I found that you can enter the blue paint pipe by using the Excursion Funnel under it. I went on the roof of the map and basically did the same thing that I now see in the posted youtube video. Still it was more intuitive to me then to use the tiles under the grate.
Still I think my way is exploiting map deffects.

Well I'll be damned.

he does the intended method, but unfortunately his method of doing part 4 isn't quite intended

Then do tell how you're supposed to solve this. Unfortunately, I don't have a guide that can tell me what I'm doing wrong. As far as I can see, it's impossible to get enough momentum to make the gap to the end in one, you can't use the funnel, and you can't bounce on the floor. So, tell me what magical solution you had in mind.

I'm going to assume you couldn't figure out how to do it right.

I'm going to assume that this test requires bullshit reflexes, pixel-perfect accuracy, a stupid amount of luck, or a combination of the three. No matter which it is, it's bad form, and this is a bad map.

Excellent map. Really good puzzle and great solution. Love it.
Thanks for these awesome maps. I enjoyed it very much.

VERY VERY HARD !!!! I can't believe I even got it.

Cunning and simple - just the way I like em. Excellent test and an excellent collection overall. Thanks.

Very good map. Good design. Simple but effective. I got stuck under the floor a couple of time but it was my fault. The cube got stuck too. It's not very important. A very interesting serie. Brilliant. Thanks.

wow, very clever champer.

I wasn't sure if that height was going to be enough, but F6 was there just in case it wasn't. :-D Tricky one. Very well done on everything. Thanks for taking the time to make them.

Haha!. Incredible test!. Tricky and clever.

Wow. Progresivly got harder as the tests went on. This was a good one to finish on, took me the longest to complete it. Very solid test chambers out of the box kind of thinking but nothing gimicky. Nicely done on all of them.
