Review — AI: The Somnium Files: an investigation adventure with an ocular AI
Uchikoshi in 2019 — not just reading text
Spike Chunsoft, 2019. Scenario by Kotaro Uchikoshi of Ever17 and Zero Escape fame. Suspense, gag, SF, parody — everything in the script, plus a cast with loud personalities. Reviews often flag crude jokes and conspiracy riffs as strong quirks, yet planted threads light up and episodes lock into truth in a way only Uchikoshi delivers — a one-of-a-kind story. Dialogue carries the plot, sentences stay short — page-turn manga pacing. It clears the old “just read text” adventure image and sits as a newer-era ADV.

Scores as listed on Metacritic and each outlet; may vary by platform or edition.
Critics mostly backed the writing, voice work, and Somnium set-pieces. The Switch Metascore ranked 12th among Switch games reviewed in 2019 on the aggregator. Pushback clustered around crude gags, uneven tone, and Somnium timers — the same fault lines player reviews still argue about.
Awards: nominated for Best Adventure Game at the 2019 Famitsu Dengeki Game Awards. Japan's launch-week sales were modest, but the PC build landed among Steam's stronger new-release sellers that month. For Uchikoshi, it was a step out of Zero Escape's sealed rooms — ocular AI and dream raids reaching a wider adventure audience, with scores that reflect both the reach and the friction.
Setting — near-future Tokyo, an ocular AI, and dream-entry Psync
Near-future Tokyo where phones and net feel like ours — YouTubers included, easy entry. Two big deltas: ocular AI Aiba in Kaname Date's left socket, and Psync gear that lets you enter others' dreams. As an AIBIS special agent, Date hunts cases with partner and device. The tagline “I killed because I wanted love” also plays on “AI” and “eye”: Artificial Intelligence, Eye, meeting (ai), and love (ai) — overlapping words that give the back half its weight.
Story — a serial-killer shell over an identity hunt
Six years after an incident cost Date his memory and left eye, he works AIBIS with Aiba and Psync. He also ends up living with Mizuki Okiura and her daughter Iris. The case opens at a ruined amusement park: an eye-gouged corpse — Mizuki's mother Shouko Saitou — and Mizuki herself on scene holding a bloody ice pick. Roughly two hours of stormy setup, yet gags and cast keep it from going fully grim.
From there the plot sinks into who the amnesiac protagonist really is. The late-game pile-on matches Ever17 — and in places may out-punch it. The culprit stays hard to pin, yet every route's facts lock together. The aftertaste is “one rope,” not “I guessed it.” The finale can feel a touch long because the answer hides so well.
After the common route, meta-fiction, suspense, and love stories stack in Uchikoshi fashion. Core theme: love — especially parent and child. Mizuki and her parents, Ota and his mother with dementia, A-set and her mother's eyes — blood ties and chosen family in many shapes. Ota's mother arc hits familiar beats but performs. By the ending, what the scenes say matters more than exposition.
Date and Aiba — a partner act with real weight
Characters keep up with the plot. It starts with Date and Aiba's throwaway banter, then fans out to net idol A-set (a hardcore conspiracy theorist on some routes), wannabe light-novelist Ota, his mother, Moma Kumakura, the taxi driver who calls passengers “granny” for a loud laugh, and more — the list does not end. Crude jokes show up often, but the case itself is brutal enough that the comedy works as a buffer. The spine is one-eyed Date and Aiba in the socket: venom and logic braking Date when he starts to run hot. That back-and-forth is how character personality fills the gaps between investigations.
Parody and memes woven into the story
Parodies and net memes are packed in. Reviews split on this — some players bounce, some lean in. Missing a reference is fine; the tone still lands without the original joke. If that register works for you, watch the margins of dialogue and the edges of the frame. Tapping something that looks unrelated to the case can still spit back a reaction — the RPG mood of doing side quests while the world ends, rebuilt as adventure “poke the screen” play.
Music and visuals — careful for an ADV, sufficient on screen
Every track fits its scene; among adventures this is a carefully scored set. The title screen atmosphere is especially strong — you feel a long story starting before you click in. Visuals are sufficient. Some event scenes look cheap, but nothing that blocks reading forward. Rated CERO Z: blood and a few brutal beats exist. It is not horror-scary or grotesque in the pull-back sense — the mystery information matters more.
Two layers: investigation and Somnium. Investigation is point-and-click across locations — hover names, color-coded new info, less backtracking hell. Irrelevant NPCs and props feed Date/Aiba banter. Aiba's zoom, X-ray, and 35mm shots help parsing. Testimony clashes and timing interrogations add bulk. Branch rewinds stay clear; choice overload and push-input friction remain.
Somnium uses Psync to enter dreams and view the subject's subconscious in third person via human-shaped Aiba — puzzle logic over real-world rules. Pulling the ice pick from a photo can be the “right” emotional read. Late Somnium gets brute-force heavy; timer stress on gag picks stays as noted.
Beginner-friendly design living with deep craft
Careful systems and deep craft sit in the same room. Route changes and retries are always available. Scene recaps in small movie windows cut down on “wait, what was that?” Mostly full voice, and a rare Switch title with touch support. The glossary notes — likely Uchikoshi's own prose — are staggering in volume, even explaining near-common-sense terms. That is why poking the world stays fun: polish and gag density share the same ground.
Somnium — where the quirks and the problems stack
Roughly: dive into a subject's dream for clues. The game's strongest quirks and weakest points both live here. Roughly half of Date and Aiba's silly banter happens in Somnium — yet the timer makes joke options hard to pick. Every action burns time; clearing with a second left and a hidden item unlocks artbook-style extras, which only tightens the squeeze. Skip and retry are easy; the chore remains. Common sense does not apply, so the “correct” move may not open the path, and finales often turn into brute force. Thin theory, slightly awkward controls — the partner comedy and the clock are arguing in the same room.
System — stable to the end; restart after long sessions
No freezes before the credits. After clearing, browsing the album crashed once. Long uptime stretches load times — periodic restarts help. More a long-session note than a show-stopper.
GPA analysis and neighboring titles
GPA tags put Story Depth and Text Adventure at 90%, Emotional Story and Multi-Ending at 85%, Existential Theme at 75%. Action sits near zero — the numbers say read, choose, and explore dreams. A mystery ADV where text, branching, and theme stack high for players who like to think afterward.

Based on GPA major tags. Action sits near the floor.
On the shelf of neighbors: Uchikoshi's Ever17 / Zero Escape for planted twists. Against Detroit: Become Human's city-scale android politics, this AI is one eye's worth of partnership — narrower, denser. 13 Sentinels: Aegis Rim sits beside it for narrative density; Disco Elysium for text-heavy reflection. Slot this after Detroit and the air changes — locked rooms and dreams instead of social movements, asking similar questions.
Polarizing gags — miss this tone and the whole game feels distant
Not calling this bad — just noting it splits the room. If the comedy does not click, the whole package is hard to accept. A shootout that looks cool can end in a deliberately stupid punchline. It is not always that register; tense scenes exist. Still, gags land in apparently serious beats, and some players will find them cold. Treat it as the on-ramp to Uchikoshi's habit of parking despair next to the laugh.
Reviewer's take
Comedy that grates lowers my personal score — yet the story holds. Not Ever17-level shock or Zero Escape-tight engineering, but resolving on ambiguous love is genius-tier craft. Strong quirks; still a new-era ADV worth playing now. CERO Z (18+). Sequel nirvanA Initiative (June 2022) sits six years later — this game first.
