Before starting this review, I would like to mention that this game is short, even for point-and-click standards. It's about two and a half hours long if you don't get stuck, and as such, I would really only suggest it on sale. I picked it up from Green Man Gaming for about $1 with my credit, and I can calmly say I was happily surprised.
Puzzle Agent is a rather unconventional point-and-click game, with a highly intriguing story, wonderful atmosphere, and great art style. I say unconventional as instead of the normal collecting objects for puzzles, you're flat out given varied puzzles, that are different every time. Are you doing a traditional puzzle? Solving a mystery? Ordering logs so you reach your destination? The variety is very nice, and keeps things fresh.
The story is incredibly well written, and full of twists and turns along the way. I won't really spoil much about it, however, this game does end on a cliffhanger that honestly turns this game into a vastly extended demo for its sequel, which is much more fleshed out, and has about double the playtime. With that being said, though, I didn't hate the ending, but it was just there. The buildup to it is great, but there are loose ends everywhere.
With as many bad things as I can say about the ending, though, the atmosphere of the game is amazing. The seemingly-normal town of Scoggins is full of intriguing characters, and it just feels right. The way people speak, the way things look, the unsettling feeling of being alone in an empty world, it's absolutely amazing, and I really wish there were more than two games in this franchise, so I could explore Scoggins more.
Graphically, the game looks great. Graham Annable's art style gives the game a really unique feel, and just adds on to the atmosphere even more. There's not really much else that I can say about it, it's shown off in the screenshots incredibly well, and looks very nice.
All in all, I would highly suggest this game on sale. If it were a longer game, I'd suggest it at an even higher price than it currently is when it's not on sale. You owe it to yourself to check this game out some day, it's worth it.
