All puzzles completed, no wrong answers, no hints used. It's been very interesting to see this example of Telltale Games' earlier work! Similar in many ways to the 3DS's Professor Layton series, Puzzle Agent is essentially a series of standalone puzzles tied together with a narrative based on investigation of a missing-person investigation by an agent of an imagined 'puzzle division' of the FBI (which despite some 'dark' themes, is told in a generally light-hearted manner). There's a nice variety to the puzzles, and while none are especially difficult, solving each once always brings a sense of satisfaction.

The game does come across as somewhat unpolished, with simplistic 'cartoon' graphics and low-frame animation, though that may be by design - and ultimately, for both the puzzles that are the game's core and the accompanying story, this was an enjoyable experience.
