Sometimes what seems really wrong... works! Just goes to prove there's no "wrong way" in Portal. Square cube not even needed at the exit.

I got it now. One has to think a bit sideways to solve this puzzle. Nice :)

Well then I give up. I could only complete it by pushing through the exit. Would you care to show us your intended solution?

Hi guys, no cheating or fancy jumping required. You can even carry the cube through the exit once you have the answer...

I think it was also, Mad Fool. I can't see any other way of completing the puzzle! Anyway - good concept. I found this puzzle when searching for other chambers with the same name as my latest one: "Misdirection". If you like a real challenge then please try it at http://steamcommunity.com/sharedfiles/filedetails/?id=140602475 - and I'd like to hear your comments :)
Induststrialzombie - you're welcome to give it a go too!

Was pushing through the exit part of the solution? If so... hmm... not sure, but I think I have mix feelings about this puzzle. If not... I think I still have mix feelings about this puzzle. Certainly a twist.
