The amount of 2 off is impressive and I agree with Alazeh: there are probably more than one 126 route.
I liked the level but remove one star because there is no apparent "trick". We try different routes until one eventually works, but why this one and not another? Not a clue...
I needed 2 tries because I started blindly without to study a bit first. It failed of course. Since there was no optimization possible, for 2nd try, I gave it a thinking first and won. That's those type of trick relying entirely on how we can get blinded at times... :D
