Lydia is an atmospheric and narrative-driven yet occasionally eerie adventure game that explores adult substance abuse from a young girl's perspective. The game delves into alcoholism and its impact on children. With a recommended age rating of 18 years, players immerse themselves in Lydia's world.

In this game, players follow Lydia, a sweet little girl deeply attached to her teddy bear, Teddy. Lately, both have been sleeping poorly due to loud noises downstairs, where adults embark on their own adventures every night.
