I think I'd prefer it if the first half remained as is (a demonstration) but the second half was given just a very slight variant to the design.
For example: put another movable next to what is now step24 and one at step28 that can go upwards.
What a great level! I was stuck first at 110 and later at 108. Reading Tilu's comment helped. I knew I had to try something different but needed to read it! :) And now I got 100 sharp. :))
