The Professor Layton games form a popular portable series that's spanned across the DS and 3DS, famous for their puzzle-based gameplay. Though fans still await the coming of the mysterious 'Layton 7', the series recently lost a great contributor on its development side.

It was recently reported that Akira Tago passed away on 6th March at age 90 due to interstitial pneumonia. Tago worked as the puzzle master on the series and had a hand in the development of many of the puzzles that appeared throughout the games. Tago was an academic and a psychologist, and before working on the Layton games he penned a popular line of quiz books called Atama no Taisō, which made their debut in 1966 and would go on to inspire the games.

We'd like to express our condolences to Akira Tago's family.
