Puzzle Agent 2

Puzzle Agent 2 is an adventure/puzzle game by Telltale Games, in collaboration with Graham Annable. Like the first game, the game structure resembles a linear adventure game - the player doesn't have an inventory, but can traverse into dialog trees with other characters. Some items or choices of dialog result in puzzles to be solved, although in some cases the puzzle has no consequence in the game's progress. The types of puzzles vary from jigsaw through maths to logic puzzles. (wikipedia.org)
