Based on Robert Louis Stevenson's classic novella, Dr. Jekyll and Mr. Hyde is a side-scrolling action game released for the NES in 1988. Players control Dr. Jekyll as he attempts to make his way to the church for his wedding while avoiding various stressors and obstacles in the streets of London. If Jekyll's 'Stress Meter' fills up, he transforms into the monstrous Mr. Hyde, transporting the player to a dark, demon-filled world where they must fight back to regain Jekyll's form. The game is notorious in the retro gaming community for its punishing difficulty and unconventional mechanics. Despite the criticism it received over the years, it remains a cult curiosity for collectors and fans of gothic horror themes in gaming.
