"Once you've finished all of the puzzles in the main game and come to the end of the narrative, you'll unlock yet more puzzles, as well as some other bonuses AND the weekly puzzles to download. Phew. If played in short but regular sessions, the game should last for a fair while, but it's all too easy to get stuck in 'just one more puzzle...' mode and end up completing half of the puzzles overnight.
All in all, Professor Layton and the Curious Village is a must buy for anyone who loves puzzles and riddles in general. It's a joy to play, and its few shortcomings - a couple of the puzzles are actually wrong and hunting for the very last few puzzles can get tiresome - are of little consequence when compared with the playability and sheer happiness the rest of the game offers."
