On level 21 (I think), one crate falls THROUGH the walkway (yes, it's a walkway not a connector) and one of my three men goes PAST the three elephants and falls over the edge!
Like others have said, often you change something on one bridge and ANOTHER bridge suddenly collapses. 3 stars - it's a shame that the physics are lacking, it would be a very interesting game otherwise. I'm probably going to try for the hard badges, but my heart isn't really in it.
Anyway... I'm giving this sequel 5 stars because I like the air of relaxation and I generally enjoy this kind of puzzles. But I'd still like to see a more difficult version - not frustrating, but more like the first game.
The first Loops of Zen was very challenging because there were many correct-looking options for each area of the grid. Entangled looked challenging at first but turned out way too easy because each piece only looked right in the right position. This one goes back to the original premise, BUT the difficulty is significantly smaller because there are only 3 orientations as opposed to 4. Why not go hexagonal, like Hexiom Connect?
I largely agree with pielikey95's criticism - please make more games like the FIRST one, don't change the main concept! That said, I still enjoyed this sequel and give it 5 stars.
