Really well done map and puzzle in such a short space! Those first 5 points are mine

Well done....took me a while to solve the puzzle - the solution is easily seen just how to get it done took a while....Excellent.. Thanks for another fine creation.

OK so I finally started this today for some weekend fun.
So seemingly simple. But of course - NOT.
As quatrus indicated "The solution is easily seen".
Then you try it . . and realize you need to replace the portal on the funnel back at the Start.
So you go back only to realize you have no way to jump up there to get into the funnel yourself.
Then you say Ahhhhh HAH !! I will simply portal in from the side and it's a done deal.
But - NOOOOO - you cannot lose the Portal that you so carefully placed at the exit.
And round and round and round it goes . . .
Will update this Post if I ever solve it. There is no video but I don't wanna see one. YET.

Someone did post a video of their solution in the comments section. It's mostly accurate except they used some strange funneling maneuvers to get the funnel behind the laser field.

If it really is quite difficult then I may change the difficulty to hard.

FINALLY.
It all boils down to one very unexpected move - and if you do not see several moves ahead, as in Chess, you are not likely to find it. The move I am referring to is placing the cube right next to the funnel reversal button instead of ON it - then funneling into the other area and shooting a quick, temporary portal to position the cube onto the funnel reversal button.

That does make this a "Hard" map IMO or at least a "Medium/Hard".
There are other moves as well which are not at all obvious but that one move was downright tricky.
Fantastic !!
