Also, lose the turrets, or be nicer to us and give us more and clearer ways to kill them. I tractored beamed some of them, lasered the others. Then when I was trying to place a cube on a button near the end, the turret corpses from tractor beaming them, would interfere.

I thumbed you up because the design is awesome, the mechanic is incredibly interesting and I love tractor beams. I would just suggest making it a little bit easier, but this is very nice for those out there looking for a challenge. Well done!!

Ok, I finished it. First off, you're crazy. This is brutal. lol, but I liked it. The concepts here are sound, the execution is were it gets a little bit iffy. There's certain elements you placed that make it extra hard that could potentially make players frustrated instead of engaged. The first button on the first area, you gotta climb one height and then lower it into the pit with the button. Raising it was a pain. It's the first one, so you should help us by gradually increasing the difficulty. Start with the easier ones.

I get that you want to differentiate which cube goes into what button, but the sphere here was your enemy because it kept rolling away from my beams when I replaced the portals.

Then, and this isn't your design, but valve's, the grating is a little tiring to look through after a while. And it's hard to find portalable surfaces because of the thickness of the mesh. I really liked what you did here, but that darn grating isn't great for visibility.
