Zen Bound 2 is a calming puzzle solving game revolving (heh heh) around wrapping objects in varying shapes in rope to cover as much of the surface area as possible.
As a puzzler, the game isn't super. The game can't really be "worked out" in terms of puzzling your way through it, it's more of a "try it until you win" sort of game. It must be said though, that the relaxation part of it is quite good.
It's one of the only games I know of to market itself as calming, and to elicit such a response so well. The only other game I can think of really is Fez. The music is chill, light and ambient, and the sounds of the rope stretching and buckling, with paint pellets popping, is rather enjoyable.
Myself, I wasn't a huge fan of the game, and eventually just wanted to get through it. I completed all 10 trees within 3 hours, with 2-3 flowers on each level usually. The gimmick of the paint wrapping can get a bit tedious, but it's still a great game for what it is; a calming experience, and not so much a puzzle-solver.
