@X1BF52 have you beaten advanced co-op tactics too? the honorary finally to the brain teasers collection

so happy to play this one, so sad this is last one

how the fuck did you even make a map this hard

A friend and I first played this map when we started our bachelors in compsci and math, 5 years ago. We were playing different Portal 2 maps, which we could solve in an afternoon. Then we came across this map. It proved to be more challenging than the others. We spent some days working it out without success, and we jokingly decided that we wouldn't allow ourselves to finish our degree until we had cleared the level. During these past 5 years we tried on and off to solve it, but always got stuck in the same places. At some point we modeled the level in Google Jamboard, and then had to migrate these notes to Freeform after Google killed it.
At the time of writing, we are both a week away from finishing our degrees. And we have finally managed to clear the level. We're both elated with the experience. Thank you very much for making this level DrFauli, we have great memories working it out. We'll be trying your other puzzles, but this time without our degrees on the line xD

My math major puzzle partner considered changing majors from how defeated we felt after our third week of being stuck.
About 3 months and countless hours spent actually trying different progressions and we finally got it. If i had to guess I'd say about 30 hours.
(Jig)Saw would be proud. I'm gonna make people who don't even really care about Portal 2 play it just for this level.
Keep up the good work. And/or tell us any other games you've worked your magic on. *Gasp* Is it possible this is your magnum opus!?

Hey I found a minor bug in this map. Doesn't affect the puzzle too much but thought you might want to know.

Took us about 3 hours divided by 2 days to complete. I'm sure that's the hardest map i've ever played. Congratulatios, that's just insane

Love your work from the few maps I've played, great & hardcore puzzle

Played with the person commenting below (after they tried a few it over many years with different friends) and our duo finally finished it. Really cool map

Really loved the way you had to use portals in Room 4

This is my favourite puzzle in any game. Absolutely loved it.
