Yeah! I can't blame you, some of the challenges are quite impossible, but the least steps weren't hard for me, but the least time!! Especially the one with all the turrets... god... got 0:52!
But honestly, If you keep try and retry, you can achieve gold even without cheats. I spent all my day from the morning till the late night to get Aperture Science... and, phew, everything is done!
But hey, I'm quite happy you enjoy your achievement now
