Long Live the Queen
Long Live the Queen is a British visual novel game published and developed by Georgina Bensley's Hanako Games on June 2, 2012. Designed in a Japanese-influenced art style, the game is about a 14-year-old princess named Elodie, who has to take the throne of her late mother but becomes the kingdom's wanted target for death. The player must keep her alive throughout her last 40 weeks until she is crowned at the age of 15.
One of the ways Elodie will die is being poisoned by chocolate. Her remains make it clear that she has eaten a lot of it.
