Play Double Target - Cynthia no Nemuri (Japan) Online

Double Target: Cynthia no Nemuri is a Japan-only release for the Sega Master System, developed by Sega. It arrived late in the console's lifespan, offering a distinct, moody alternative to the brighter, faster platformers common on the system.

You control two characters, a man with a gun and a psychic girl named Cynthia, switching between them to navigate a surreal, maze-like hospital. The man shoots enemies on sight, while Cynthia can phase through certain walls to access hidden areas or evade threats. Your goal is to explore room by room, gathering items and uncovering the source of the nightmare. The pace is deliberate, the corridors tight, and mistakes are costly. It feels like cautiously unraveling a bad dream where every corner could hide something unsettling.
