Gosh, that was unexpectedly difficult. Took me a good while to actually reach the exit and stuck at 2off. The eventual correct solution didn't seem right.
This is a particularly interesting level because newbies will eventually feel their way to a solution, but it's got enough layers that newbies may not understand the lessons to be learned immediately. It gives them a taste for more modern designs and the expectations of some harder puzzles.
I think MANY levels in this world of yours are suitable for learning, for beginners. Very good levels, in my opinion! Especially this one, which gave me some trouble, too, even after I've gained about 97 % of the whole game. :D!
