I finished Hitman GO. It was a pretty good puzzle game, though some of the optional objectives were very hard, especially the minimum-moves challenges. I haven't played anything in the Hitman series apart from this, so if the levels here are references to those games, I didn't get them, but everything before the reboot is in my backlog to play eventually.
I don't enjoy difficult puzzle games because they tend to have only one solution for each puzzle, and it's very irritating if I can't figure out what that is, so I don't expect to play much more like this anytime soon.
