I cried. I screamed. i laughed and most of all I died 1000 times. +rep

Quite challenging. I agree TS_Mind_Swept's checkpoint criticism. Except in our run I was the one who screwed up heavily :-/
Thumbs up.

Reached all parts of the maps but still had no clue what to do next.
Had to watch youtube solution multiple times to finally understand how to progress.
11 out of 10 for the map.
Small spoiler: Boxes can pass through the fenced portal wall unlike players.

Quite challenging. We felt a real sense of accomplishment reaching the exit.

no, it isn't, that's why 6.5.

6.5/10 though? Really? Keep in mind that this was one of camerson1313's earlier maps, beofre he got BEE2 (and even then autosaves don't really work 'cause its coop). Also camerson1313 is known for making increasingly difficult (but worth it!) maps, especially for coop xD

Finally, without the consequence of death, is this even Science?

don't you "buddy" me.

Actually, this one is better than you think buddy ;P

Oh Tutankhamun, that was a pain, just when i thought it was going to be over, it got twice as long. And I'm not going to say any names ( p0rtalmaster !) but my partner died a few times and screwed things up a bit, i wish this one was a little better on the "checkpoints" in the sence that you don't have to redo as much when you (or your "friend") screws something up. Will be playing more, but this one is not my favorite. 6.5/10

Awesome puzzle, so happy to have all these good co-op puzzles. Me and my friend are always on the look out for challenging co-op puzzles and glad that you have 30+ of them. Thanks.

yay! solved this map in a good time - got us thinking even more than the last one! =)
Really nice puzzles and a good overview - well done mate!

one question though:
We are not sure about the way back from the upper funnel room...
Here is what we did:
1.) Player with the funnel goes in upper room
2.) one portal on the floor (in upper room)
3.) one portal on the angled panel => and go through that portal
4.) jump over the goo (it is possible to jump that distance without strafe jump)
Just let us know, if this was okay, or if we have to rethink that part.

Great Puzzle took me and my Friend quite awhile to figure it out love your puzzles keep up the great ideas.
