'Back Then' is a narrative-driven first-person atmospheric adventure game, about an elderly poet diagnosed with Alzheimer's Disease, who struggles to keep his Being and Memory in his fight against Time. Thomas, feeling his own mind start to betray him due to the disease's consequential memory loss, searches through his mementos and souvenirs for the happy memories of his family and lifetime in a last attempt to keep them. Guided by different ghosts of his life, he explores his mind throughout four seasons in an attempt to reconcile with his family and himself as he struggles against Alzheimer's and the loss of his soul in both past and present.
