Double is an adventure game developed by TomatoFantasyGames for Windows. The game revolves around Carlos, a PTSD patient who wakes up in a psychiatric clinic. His only chance of recovery is to delve into his nightmares and gather information. But as Carlos delves deeper, the line between reality and nightmares begins to blur, making it difficult to distinguish between the two.

The gameplay of Double is divided into two worlds - the real world and the dream. In the dream, the gameplay is a psychedelic 2D shooter with cover-based gameplay, where the boundaries of possible and impossible are erased. In the real world, the gameplay is a quest based on dialogue and choices, where the development of the plot depends on the decisions you make.

The game features references to real events and a unique Cuban setting, which is enhanced by the traditional and modern music used in the game. Double is an immersive adventure game that challenges players to explore the depths of Carlos' mind.
