One of those delightful sequels that expands everything the first did well without coming across as bloated. The islands are drop-dead gorgeous, the puzzles are ingenuous and rarely frustrate, and there's so many little secrets littered about here and there.

More importantly, the philosophical questions that felt rote and shallow in the first game are given greater depth here. You're no longer reading what-ifs on terminals isolated from the rest of the world: you're surrounded by characters invested in your journey, as well as the future of their own city. Even when it gets obnoxious at points, there's a degree of humanity on display that makes each stray thought easier to swallow.

Anyway, this is one of the best puzzle games we've played in years, and we'd happily recommend it to anyone.
