Pixel art has trained a lot of us to expect something gentle, low stakes, maybe a little nostalgic. This one used that expectation against me almost immediately.
Ronnie is barely a month into his new job when he starts pursuing his boss, a woman who goes only by Miss 3456. That numeric name turns out to matter a lot more than it first seems once the story actually gets moving. Fif, working entirely solo across art, writing, and music, built this pixel-art visual novel in 2023 around that budding office romance, set inside a futuristic sci-fi world that the game itself frames as part of a much larger, ongoing universe. The official description leans on crime as much as romance, and that framing turns out to be accurate rather than decorative, since the story eventually pulls in stakes well past a simple office crush gone complicated. That crime thread stays woven directly into the romance rather than sitting off to the side as a separate subplot competing for attention throughout the runtime.
Choices show up mostly early on, clustered in that opening stretch before the story settles into a more linear groove. Any bad ending I ran into simply looped me back to the last branching point rather than ending things outright, a forgiving structure that suited how much of the game’s tension comes from what you learn rather than from punishing wrong guesses. That structure kept me exploring without much fear of losing real progress. It made poking at Miss 3456’s guarded personality feel low risk even as the story around her got progressively stranger with every passing scene. Ronnie’s own eagerness, chasing a woman who reads as clearly older and more composed than he is, plays into a genre convention the game leans into on purpose rather than by accident, one familiar enough from other yandere-adjacent romance stories that I recognized its shape well before the story’s stranger elements even started surfacing properly.
Something about Miss 3456 never quite reads as fully human. The story eventually threads that unease through a central concept involving a synthetic or engineered body, one that reframes everything about who, or what, Ronnie has actually been falling for this whole time. I won’t spell out how that thread resolves, only that letting the mystery breathe rather than rushing to explain it gave the romance itself real tension it wouldn’t have had otherwise. The story trusts you to sit with unanswered questions for considerably longer than most games this size are usually willing to risk.
Every frame stays committed to that pixel-art identity, characters and backgrounds alike rendered with a level of expressiveness that outpaces what the format usually allows, small character animations doing real emotional work in moments where a static portrait would have left the scene feeling flat. There’s no traditional voice acting anywhere. Dialogue gets punctuated instead by small, distinct sound effects clearly reminiscent of Undertale’s text-blip style, a choice that gave conversations a rhythm text alone couldn’t manage, each character carrying a subtly different blip that made them recognizable even before I’d read who was actually speaking. The score carries its own layered identity too, with separate musical motifs tracking different facets of Miss 3456’s presence throughout the story. Those shifts stayed subtle enough that I didn’t consciously notice them until I’d already absorbed what they were signaling about which version of her a given scene was actually showing me. Knowing one person handled every part of that presentation, the pixel art, the writing, and the score alike, makes the finished game’s consistency feel even more deliberate than it would from a larger team splitting those responsibilities across separate specialists. Nothing about the game reads as though different sections were stitched together by people working from different creative playbooks.
The romance itself ended up mattering less to me by the end than the creeping suspicion that I didn’t actually know what I was rooting for in the first place. Every scene that deepened Ronnie’s own feelings also chipped away at how confident I felt about Miss 3456’s real nature underneath it all. That specific kind of uncertainty carried more weight than a straightforward workplace crush ever could on its own.
Cost stays at zero across Steam, itch.io, and mobile through TapTap. Chinese localization support gets built directly and fully into the Steam release, accessible through a simple language toggle in the game’s own properties menu for anyone who needs it. It also connects loosely to other titles from the same creator, including The Merciful Savior, a separate story about a young man growing close to an online friend, one that shares this exact same wider universe despite following an entirely different cast of primary characters. That companion piece revisits Miss 3456 from an entirely different, unexpected angle, showing off a more lighthearted, otaku-leaning side of her personality alongside a new character named Monate, and it deepens the shared lore just enough to make both games feel like pieces of the same larger picture rather than one-off standalone stories. Seeing a character get reinterpreted this differently across two connected releases, still recognizably herself but tonally shifted depending on which story she’s appearing in, says something about how deliberately Fif built this universe to support more than one perspective on any given character within it.
Verdict
BLACK BOX LSS – The Shining Immortal takes a cute pixel-art shell and fills it with real, sustained unease, using a workplace crush to smuggle in a much stranger story about what Miss 3456 actually is underneath everything else. Ronnie’s eagerness against her guarded, numerically-designated identity gives the romance real stakes beyond the usual boss-and-new-hire setup. The crime elements woven through that structure earn their place rather than feeling bolted on for extra flavor. For a free, solo-developed project spanning writing, art, and music all from the same person, it’s a remarkably confident, well-assembled piece of work that trusts its mystery to do the heavy lifting rather than leaning on shock value to carry the ending.
