Compare Mr Investigator prices across trusted key stores and find the best deal. Developed by Haoning Wu. Published by Haoning Wu. Released on 1/10/2026. Available on PC. Genres: Adventure, Indie.

A solo-dev murder mystery that locks you in a black-and-white British autumn and refuses to hold your hand, earn every deduction or go home.

I keep a mental shelf for one-person passion projects that slip past every algorithm, and Mr Investigator earned its place on it. Haoning Wu built the whole thing alone, and that handcraft is visible in every choice, from the deliberate pacing of the Time Bureau's world-building to the quietly confident decision to strip the visuals down to black and white. That visual direction, openly nodding to Return of the Obra Dinn, ends up being more than aesthetic. The monochrome palette focuses your attention exactly where the game needs it: on the text, the memory fragments, the gaps in the timeline you are responsible for filling. The setup is a first-person detective puzzle set in autumnal Portsmith, England. You are an agent of the Time Bureau, and your job is to reconstruct an unresolved murder by moving through written memories, essentially reading the victim's diary as scattered, nonlinear fragments and rebuilding the chronological truth from scratch. There is no hint system nudging you forward. No objective marker. The satisfaction comes from the moment you connect two fragments that seemed unrelated and suddenly see the shape of what happened. Players in the community have noted that the puzzles carry genuine difficulty, with at least one describing moments of feeling genuinely stumped rather than guided, which, depending on your tolerance for friction, is either the game's best quality or a reason to walk away. There are some rough edges worth naming. The game launched in January 2026 as the work of a first-time developer still learning the engine, and some early players observed that it felt close to but not quite at the finish line in terms of polish. Puzzle design in places has drawn questions about clarity of intent versus genuine obscurity. The community has begun posting reasoning guides, which speaks both to the game's difficulty and to its cult appeal. A dedicated player base working through a hard mystery together is a good sign, not a bad one, but it does mean you should go in prepared for genuine challenge. What Wu gets right that larger studios rarely bother with is the specificity of atmosphere. The setting has a mood, rainy English autumn, a grief-soaked case involving a client's father, a bureau that feels like it has history, and the writing leans into it without over-explaining. The nonlinear diary mechanic is not window dressing; it is the whole puzzle, and sorting the timeline is both your core loop and your emotional arc. Themes of grief and suggested violence sit underneath the logic game, giving the deduction weight that a pure puzzler would not have. If you genuinely enjoy sitting with a mystery that will not yield until you earn it, this is worth your time. If you bounced off Obra Dinn the moment guidance dried up, the same friction is present here, compressed into a smaller but no less committed package. Kai, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
