Sophia, Kat & Rin from Wimbledon won the Game Concept Award (15-18 year old categeory) in 2018 for Tea & Tartlets.
Tea & Tartlets is a top-down story-based simulation game in which the player runs a café and progresses through the game's levels - unlocking new recipes and perks - with a romance-focused story intermittent throughout. With a target audience of pre-teens, teens and young adults Sophia, Kat and Rin wanted Tea & Tartlets to be an inclusive game that will encourage an interest in cooking and running a food or restaurant business. At any level, a food critic could make a surprise visit and have the café closed down and this is when the romantic interest will help out the player character.
