Great map! It took us three passes to solve it completely.
We first found an alternative solution - https://youtu.be/IYHGAUVWr9o
But in this case, the staircase going up at the push of a button was not used.
As a result, we figured out how one robot should help another get up.
But the ending we again turned out to be different from the correct one - https://youtu.be/MNNSKoDm4vs
We enjoyed it a lot, and we hope to one day play the next map in this great "Piece of Cake" series :)

Thanks for your kind comment! Lots of fun building these (lots of "arrrg broken again" too..), I don't know if there will be more, not in portal mood recently (also, portal mood is something dangerous: you wake up in portal, you shower in portal, you drive and work in portal...)

2/2
Congratulations, you have a real talent for chamber making. Thank you so much for creating. Since P.o.C.-2 is a goddamn 11/10, this one has to be an 8 :-P
My rating of the series: 1<4<3<5<7<6<8<9 (no 2 is out of competition :-P)
Although I very much favour the double laser puzzle ideas from #8, I prefer the chamber size of #9. It made me feel more comfortable.

Dude, what can I say... FANTASTIC finale! (so far - will there be more in the future?^^)
We spend about 2h 45min in it. It was highly entertaining nonetheless! <3
It was so hard to find the correct order of most of the single steps, and it was just as hard to reconstruct it once we messed up our portals... again xD
The chamber has a beautiful compact design, you can see and understand everything - respectively you can guess what will come but it's hard to accomplish ;-)
I also must praise the momentum build up mentioned by Hackerman :-) The timing in the end is just right. We were thinking about it for a minute so we were able to realize that it doesn't have to be done in parallel. But does it have to be a timer? I'd rather like to see it as a permanent checkpoint. This would lower my adrenaline ;-)

Thanks for your comments and glad you liked it!

Well done on this map. By far the hardest and best map I've ever played :)

This is truly a master piece. It had me stumped. Tried solving at 2 A.M. and boy was it hard.

and thanks for playing! In description, I write "3/10 is for campain difficulty", so I think 6/10 is ok, compared to some of my others maps ^^ (like P.o.C-2 or solo ones). Yes, focusing on blue funnel was the trap :)

This was a lot of fun. I think it's much harder than a 6/10 logic difficulty. The bit we got stuck on for an hour or so was the multiple quick portal shots to "bounce" one person up towards the orange funnel. We kept thinking the only way up was using the blue funnel. We also did the ending in the most ridiculous way: Had both people come up to the square button, then do a frantic dash where we both fell down into the orange funnel and leaped over the edge to fall at the same time. The timing this way was super tight, I should have realised there was a better way but by then my brain was tired. This is definitely my favourite of your maps, thanks for making.
