Something special about level 32, 64 and 96?

Why do so few people have those levels completed? I just played through the whole game in an hour and I can't see why so many people would have skipped those three levels.

I am stuck at level 67 to be honest the tip tells me to draw a square
I suppose I am just bad at drawing squares :D

Edit: It took me a bit longer to complete 2.2 hours

for some it might not be so straight forward where to draw the lines, compared to others
it was fun to play and easy to complete nonetheless :)

I think those achievements were bugged for the people.
