Thanks for your kind feedback! I've set the level from very difficult to difficult.

That was a lot of fun, so much so I did it twice after irreparably failing the start! I like how it feels as though a unique parity is being applied, and it flows very smoothly all the way. Even though I failed at first, that's just because my solving skills are mediocre, and I wouldn't say it's very hard, which is not to its discredit.
