About Device 0101

Device 0101 is a mystery action-adventure puzzle game developed by sadari games and released on December 4, 2025, for PC. It follows Risa, a girl who wakes up in a mysterious mansion after a birthday argument with her father. The game blends exploration, combat, and logic puzzles as players navigate a shifting environment to uncover secrets. Set in a surreal, eerie mansion, it leans into indie and fighting genres to create a tense escape scenario. The story hinges on Risa’s choices and the mansion’s unpredictable dangers. It’s a compact single-player experience designed for players who enjoy solving environmental puzzles while fending off hostile creatures.

Gameplay

Device 0101 tasks players with solving puzzles to unlock doors, combat monsters using melee and ranged attacks, and backtracking through the mansion as new paths open. Each room contains logic-based challenges like repositioning objects or adjusting light sources to reveal hidden mechanisms. Combat is fast and aggressive, requiring timing to dodge and counter. The mansion’s layout changes subtly between sessions, forcing players to adapt. Players collect tools like a flashlight to manipulate the environment and unlock secrets. A typical session involves balancing puzzle-solving with survival, as enemies respawn if too much time passes. Controls are responsive, but the game demands precision in both fighting and puzzle-solving.

What Players Think

PlayPile community ratings for Device 0101 average 4.3/5, with 82% completing the main story. Players report an average playtime of 12 hours, though 25% spend 18+ hours due to backtracking and optional puzzles. Community moods lean toward curious (68%) and tense (54%), with some frustration over combat difficulty. Critics praise the mansion’s shifting design (91% positive reviews on Steam) but note pacing issues in mid-game sections. Achievement completion rates are high at 94%, with 30% unlocking all secrets. One player wrote, “The puzzles feel rewarding, but enemies can be unfairly punishing.” Another noted, “Worth it for the atmosphere alone.”

PlayPile's Take

Device 0101 is a solid pick for puzzle fans who don’t mind aggressive combat. Priced at $29.99, it offers 10, 15 hours of core content with optional challenges. The mansion’s evolving layout keeps exploration fresh, but fights can feel repetitive. Achievements are plentiful, with 40+ to unlock. It’s not perfect, puzzle-combat balance stumbles in key moments, but the eerie vibe and clever environmental design make it memorable. Prioritize if you enjoy atmospheric mysteries and don’t mind tuning into a tense, occasionally frustrating experience.

Storyline

Risa argues with her father on her birthday and leaves the house angry. And head to a pojangmacha near the beach, the meeting place with friends who were supposed to meet on their birthdays. Risa and her friends celebrated her birthday drinking together. I don't know how long it's been since then, but Risa opens her eyes on the bed, not the pojangmacha, and the story begins.
