[Coop] Double Jump
A 1970 styled coop map. It contains repolsion gel and hard light bridges.
And jumping in mid-air.
This is my first coop map, so feedback is appreciated.
That was good fun! 
The chambers look very good and it's very nice how the test elements have to be reused slightly different each step. I'd have nothing negative to say.
One suggestion: I would let the trigger_hurt do 1000 damage or similar. That way, players would die as soon as they fall in the water. Right now, they die so slowly that there is time for two explosions. I think it would be better to just have them respawn asap since it's clear they are dead anyway.
In the first chapter, there are some exploits possible that Mumbles found when we were playing it. But they should be easy to fix:
Spoilers for parts of the correct solution, don't watch before having played it yourself!
I finished it solo with 2 portals

Nice!
Oh, I thought you meant that not only did you finish it solo, you shot a portal only twice. I solved the first test, good map so far.
Liked the map, not and difficulty to speak of, but really fun with all the jumping.
