I don't understand how a 3 column level manages to have this many possible options, and still manages to hide a crucial concept behind everything. One of the best levels in the game, but it is very very hard.
Genuinely don't know how I got so completely mindblocked on this that it took me 2 weeks to solve. Through logic, I eliminated an option that was clearly possible. For what it's worth, I think this is one of the best levels in the game, despite how aggravatingly painful my mistake was.
The level is amusing to work out initially, but unfortunately I think once you figure out the logic, mapping out the level just turns it into a trivial maze. This is not a negative trait of the level itself, but it does mean that variations of this structure are much less interesting after you've solved something like this once. Its size just means that you're rewarded for understanding it, as not understanding makes the level much more painful to solve.
