Impressive visuals and unique retro-inspired aesthetic that evokes nostalgia for games like Super Mario 64 and old-school 3D platformers.
Outstanding soundtrack and sound design that significantly enhance the atmosphere and emotional impact of the game.
Strong atmosphere and liminal spaces create a compelling surreal and eerie mood, with effective use of exploration and platforming segments.

Gameplay heavily leans on walking simulator mechanics with minimal platforming, often leading to long, uneventful, and repetitive sections that feel like padding.
Story is abstract, minimal, and sometimes confusing or hamfisted, with heavy reliance on references to other games rather than original narrative content.
Level design includes large open spaces and mazes that can be frustrating and tedious, compounded by lack of save system and limited replay incentives.

The story is generally seen as simple, abstract, and somewhat disjointed, relying heavily on atmosphere and vague narrative hints rather than a clear or compelling plot. While some find the mystery intriguing and appreciate the melancholic tone, others criticize it as unfocused, minimal, or overshadowed by references and gameplay pacing issues. Overall, the story serves more as a backdrop to the game's mood rather than a strong, engaging narrative.
- “The mysteries, the music, and the story are incredible!”
- “I enjoyed the liminal experience mixed with references to old games, and playing the game a few more times to find all the secrets and piece together the story (I currently have all except one achievement).”
- “The story is a bit abstract, but the dialogue provides just enough context for the message to be clear.”
- “This game is almost perfect if you don’t think too much about the story or whether everything makes sense.”
- “The story comes off as unfocused and at times pretentious mess.”
- “There is barely any actual story in this game, and it's all just a haphazard mishmash of video game references.”

The game's graphics feature a distinctive low-poly, PS1/64-inspired aesthetic that many users find visually impressive, atmospheric, and nostalgic, especially for fans of retro and surreal styles. While praised for creativity and unique environments, some feel the visuals offer more potential than the overall experience delivers. Overall, the graphics stand out as the game's strongest aspect, appealing to those who appreciate vintage and haunting game art.
- “I like the references to the classic games but with a horror hint; the levels have a specific low-poly aesthetic that I really appreciate.”
- “The devs clearly have a talent for crafting impressive visuals and atmosphere.”
- “If I had to describe the feeling of playing this game, it’d be like "drifting into a dream in the early 2000s." There hasn’t been a 3D platformer with this unique of an aesthetic and atmosphere in recent memory; it’s a breath of fresh air.”
- “What frustrates me is that the visuals and mechanics offer so much creative potential.”
- “Regrettably, beneath Oyasumii’s undeniably striking aesthetics lies little substance.”
- “Maybe it's a bit short; I would have liked to explore more levels with different aesthetics.”

The atmosphere is widely praised for its haunting, surreal, and nostalgic qualities, effectively blending eerie liminal spaces with evocative music and lighting to create a compelling, dreamlike experience.

- “Same goes for the overall lighting and atmosphere, really captures the whole dark-surrealist liminal space vibe that comes with a lot of old games.”

The gameplay in this game is a mixed bag, featuring some enjoyable platforming mechanics and creative obstacle variety, but often suffers from extended, slow-paced exploration akin to a "walking simulator" with limited interactivity. While the visuals and atmosphere are consistently praised, many find the gameplay lacking depth and overly padded, detracting from engagement despite occasional fun moments and solid underlying messages. Overall, it's more an immersive art piece than a mechanically complex or narratively rich experience.
- “I enjoyed the platformer segments and the many mechanics it introduced, as well as its attempts to diversify obstacles to match given stages: like how rain levels have slippery slopes, or having to slide through small crevices that could easily be overlooked at first playthrough, admittedly very smart stuff!”
- “The message behind the game is solid, and the gameplay itself is fun.”
- “Its a cool pixel style horror liminal game with fun gameplay and trippy levels and effects.”
- “In terms of practical gameplay, Oyasumii suffers from a severe case of the dreaded 'walking simulator syndrome.'”
- “The devs clearly have a talent for crafting impressive visuals and atmosphere, but the gameplay is, if I'm being brutally honest, kinda terrible.”
- “The issue is that usually walking sims make up for their lack of gameplay with a great and engaging story, or insanely interesting visuals and setting (like Yume Nikki, which this game tries desperately yet fails to be), but this game has neither.”

- “The OST is phenomenal, nailing the Y2K, Aero feel while staying in sync with the environments.”
