The upper part was kind of easy for me, but the lower part was a different story. I first had only a 170 path, later I found THREE different 168s, and then with a really strange combination got the 166. This was really VERY WEIRD. LOL :))
The interactions of the blocks on the right half is interesting and I liked the design. I had to maneuver carefully to get the right side. I am still 2 off, shall come back to this later.
Reading alazeh's comment I come to try this and I discovered the secrets of this chamber. I hope there aren't any more secrets as well!
I enjoyed the solving and liked the puzzle.
Hate to deduct half a star, but the solution is obviously unintended by the author (considering the original stepcount of 442...).
