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...
This took me like 30-40 tries, lol. I have no idea why this path is faster than any of the others that get me 2-4 off, but it's a great challenge and well-designed all the same. Classic ybbun stuff.
Fun. Not as bad as I remember it... Also took me just 2 tries, but I remember when it was first published I tried like 12 times with no success. No major awesome tricks, just optimization.
