Nice !! Admittedly, I was stuck completely for the longest time - and began using out-of-the-box thinking. I dreamed up a crazy way to get the cubes to the exit platform. The reason was that I assumed the little area there, with the small fizzler and portable surface at the end just had to have "some useful reason" for being there. I knew that the author would *
never add something in for NO REASON*.
So, since I was stuck, I started to allow my thinking to expand. I thought that maybe if you shoot a portal just behind the little fizzler and then store the cubes just inside that little, strange area - that there would be some way to deactivate the fizzler, and then - home free. But I was ### SADLY MISTAKEN.
And mentally, I was still stuck in that mode of believing that the Author would never add something in for no reason. Well it suddenly dawned on me -
that - in another area of the map - you had added a friggin' floating world FOR NO REASON WHATSOEVER !!!
So I realized that this tiny, "must have a reason for being there", 2 x 3 foot fizzler room - - - was nothing more than a Red Herring . . . inserted for no other reason than to mess with us students (you know us . . we're the ones who failed Portal 101 at the Local Community College). LOL !!
In all seriousness, that would have been a cool addition to the puzzle. You could have had a button at the top of that tiny area, so that once 3 cubes were stacked, the button is activated and the fizzler deactivated. Oh well, just an idea.
GREAT MAP, DUDE !! 4.5 stars rounded off to 5.
