You don’t have to be pixel perfect. Despite the game saying you need to be exact, the lenses can actually be pretty far from their intended position and they’ll slide into position once they’re all close enough. Did you actually play the game?
I’ve watched the magnifiers shift over a pretty big amount once everything is close enough. It’s not a blatant lie. I apologise for being snide and implying you hadn’t played the game, though. That part was rude. It’s rude when you say it too, but I reap what I sow. I just think that calling the game pixel-perfect is unfair, because it’s actually quite lenient. I don’t know if it’s bugged in some way to need more precision from you, but I actually felt that I could be pretty inaccurate and still beat the levels, so I’m unsure what’s causing the difference in opinions here.
