Completed Puzzle Agent recently. It was such a fun game and luckily the sequel went on sale a few days after I finished it. The puzzles were a balanced mix of 10-second teasers, those where your only hope is to jump in and work through possible solutions, and those where you really need to pay attention.
Aside from the puzzles, the other aspects of the game are no slouch either. The story draws you in and has quite a few surprises. The art work is simple, high quality, and infused with a playful sense of humor. Can’t wait to start the sequel.
