Puzzle Agent is an amusing puzzle game in the vein of the Professor Layton series on the Nintendo DS, where a narrative is played out interspersed with (seemingly random and often unrelated) visual puzzles which the player must solve. The puzzles are fairly easy (with one or two exceptions which are QUITE obtuse), and shouldn't cause most people much trouble. Furthermore, it's worth noting that the game is rather short, and the story ends rather abruptly (to be continued in the sequel). It's not a "to be continued," mind you, but....well, you'll see.
The story is....weird. It is to be experienced. It's kinda the point, and is rather surreal (in a literal sense). I found it amusing, but my sense of humor is nicely warped, so that's not too surprising. It might not be for everyone, but I'd recommend it.
