伊勢志摩ミステリー案内 偽りの黒真珠

Retro Mystery Club Vol.1: The Ise-Shima Case is a 2019 adventure game. It is a mystery-themed game set in modern-day Tokyo where the player takes the role of a detective along with their partner Ken. After the discovery of the death of a homeless man, various clues are left behind, leaving to an incident that involves black pearls. The game began development in 2010 when the game's producer Junji Seki met with manga artist Arai Kiyokazu to collaborate on developing an adventure game. While initially planning a game for feature phones, they found the market for such products failing and put the project on hold for a few years. Seki went independent in 2012 and founded the company Happy Meal, in which he was the only employee. The producer said the project got back into development around 2017 originally for the Nintendo 3DS before moving the project to the Nintendo Switch at the behest of the publisher. The game is purposely done in a retro-style of Family Computer, or Famicom adventure games, in terms of graphics and gameplay. It was released in Japan on January 24, 2019. It received a positive review from the four critics in Famitsu. A crowdfunding campaign was made for the sequel, which reached its goal in two days, leading to the sequel Retro Mystery Club Vol.2: The Beppu Case (2022).
