I hope this position will be a little more challenging. It was submitted as a helpmate in 10 problem (Evgen S. Orlov, 5516 The Ural's Problemist 60 2009). Why is it illegal?

The b pawn couldn't get over the the right! It can't get to the f or h file because if it keeps on capturing, it'll be on f6 or h8 (and actually promote in the latter scenario), not f3 or h5.
I don't follow that. Black's original b7 pawn can get to the c-file with one capture. White's original b2 pawn can get to the c-file with one capture.

I don't follow this either. Which board is upside down? Which move is sneaky?
Do you have an explanation for what makes the position illegal?
Not even close
Too many captures
