- Surreal horror with a Y2K vibe… A nightmare that blurs the boundaries between dreams and reality
- The peculiar cooperation worked… Praised in the community as a ‘great game to play with friends’
Solo developer itamu and publisher Oro Interactive have unveiled the 1-4 player co-op horror adventure ‘Mama’s Sleeping Angels’ . Officially released on PC (Steam) on March 11, 2026, the game currently maintains a ‘Very Positive’ rating with a 93% positive rate, recording 455 positive reviews out of 486 user reviews.
The game is a horror adventure set in the dream world of a goddess, where players must survive by collecting cursed items. Players must explore unpredictable, nightmarish spaces and cooperate with teammates to confront various threats. In particular, the unique system where roles persist even after death, combined with a bizarre worldview, delivers a distinctive horror gaming experience.
An ordinary night turns into an endless nightmare
The game starts with an ordinary pajama party with friends. However, as the night deepens, reality becomes distorted, and the protagonists become trapped in the dream world of an endless nightmare called ‘Mama’.
The goal is for the player to wander through Mama’s subconscious, collect cursed objects, and use them to satisfy the hunger of ‘Mama,’ an eternally starving being. However, while collecting cursed items satisfies Mama’s hunger, the price comes back to the player.
Unpredictable dangers such as vision-distorting hallucinations, sudden environmental changes, and the appearance of unidentified pursuers continue ceaselessly. In particular, the moment Mama’s hunger returns, the player is reduced from a hunter to ‘prey’.
6 dream worlds, a nightmare unfolding anew in every round
The game features a total of six procedurally generated dream worlds. The structure changes with each playthrough, unfolding bizarre and unfamiliar spaces such as neighborhood alleys, sewers, endless foggy corridors, and giant structures hanging upside down. The crude, low-resolution visuals reminiscent of the PS1 era actually intensify the surreal horror atmosphere.
Players confront threats in the dream world using firearms and ‘masks’ that permanently alter their abilities. Cursed objects collected during exploration can be analyzed via mobile phones, and information on creatures, curses, and items encountered so far can be checked through a computer inside the house. Weapons are diverse, including sniper rifles, assault rifles (FAMAS), and chainsaws.
Strange cooperative rules that save with a kiss and resurrect with a decapitation
The most distinctive feature of ‘Mama’s Sleeping Angels’ is its unconventional cooperative system. Fallen teammates can be revived with a kiss, and when a member is on the verge of death, beheading them is actually the faster method of resurrection.
Deceased players can use their wits to return to Mama’s Altar, where they can take on a support role by using an old mobile phone to alert teammates exploring to dangerous areas or send warnings when there are signs that Mama is waking up.
NPCs in dreams are not merely background decorations. If they have met the player before or shared an emotional connection, they remember this and react differently during subsequent encounters. It is a structure where relationships build even within a space that unfolds anew in every playthrough.

On the one hand, opinions have been confirmed that the tension is high due to the significant variables in the difficulty and curse systems, while the unique cooperative gameplay, which blends horror and humor, is cited as the game’s greatest appeal.
