I find that one good, because it's a board to teach that appearances can lead to wrongly apply habits... LOL
However, that one of the start lock is a fake, kills a big part of the challenge. This level deserves a 1 but not a 2 therefore.
I got it 1st try, 'cause I was trying something simmilar on the Security 2
Great level! But I prefer Security 2 to this one! :) (perhaps because I played it first).
