I found them less tedious this year. Maybe not easier, but some times earlier years I've felt that I know how to solve a problem, but it's so many cases to consider that I won't bother coding them all up (probably means I could've solved them more cleverly, though). This year it was more straight forward. Except getting rotation in day19 right I guess, which I didn't bother.
