You can skip some functions and solve it with just one sphere.

This map is all about spotting the places where you can put your portal and then grab a cube
place the cube, walk back over and over again. Once you know that you just search for the next way to put a portal or laser and get to the next plattform.
Not so much a "thinking" puzzle but literally a puzzle puzzle.

Loved the way you had to transfer the balls.

I must've done it incorrectly cause I only needed one ball. from the first ball button you can jump onto the catwalk with the ball to the second ball button. Is this intended?

Great room! I loved the juggling aerial faith plates. However, on small thing, there is a cheesable spot at the top of the steps after placing the edgeless safety cube on the second to last edgeless safety cube receptacle where you are simply able to jump onto the railing and jump over the edge grabbing the edgeless saftey cube while falling and shooting a portal down at the start to get back to the last receptacle.
