Hopefully if you’re reading this, you’ve already played through Detective Mimo. While this article will not provide a comprehensive walkthrough of the game, it does break down the game’s two endings, as well as walking through the secrets contained inside the developers’ secret room, pictured above.

If you’d prefer to experience the game yourself, skip this article and play the game, or read the spoiler-free review, instead. This article will assume you’ve finished the game, and spoil some key moments along with the final optional puzzle trail.

A Puzzle Game Built with Smartphones in Mind
As established in the previous article, while Detective Mimo initially positions itself as a puzzle game centered around stopping a bank heist, players learn there’s another layer to the game shortly after Mimo “solves the case”. After completing the game’s first cycle, Cat Rogue reveals his true intentions: hacking Detective Mimo‘s code, and rewriting the game in his own image. And that process starts as soon as the player resets the game, at Mimo’s urging: players are returned to a glitched out version of the Police Station, and the game’s text has been replaced with gibberish.

As before, the Police Station serves as a tutorial for players. But while the first cycle taught players to leverage point and click gameplay mechanics, the second cycle taught them that the game’s mechanics themselves are the puzzling playground. Since this is a tutorial mission, a neatly placed QR code on the desk instructs players to eliminate the gibberish by going to the game’s language settings, while Mimo’s faceless visage is fixed by “stealing” the face off a TV news report running in the background, and superimposing it on Mimo’s icon in the game’s dialogue box.

This style of gameplay continues throughout the second cycle: a desk that previously unlocked by swatting a mouse on a spring with finger swipes now requires players to vigorously shake their phones. Restoring power to an electrical panel that previously relied on a logic puzzle now requires physically plugging your phone into a charger. Bypassing a “quantum decoder” requires placing your phone upside down, waiting for the phone’s light to flash, and then transcribing morse code in order to generate a dynamic three-character passcode. These are all puzzles that could only exist on a smartphone, and each challenge is clued well enough to unambiguously lead to the solution without robbing players of the thrill of realization.

Which brings us to the end. Or rather, the ends.

Sometimes, Choices Are Irreversible: A Tail of Two Conclusions
Once Mimo hacks into the Machine Room’s Command Console, she urges the player to type “END” and put an end to Cat Rogue’s Doomsday Program. Cat Rogue opposes that by throwing some of the game’s hardest puzzles at the player, before deleting the contents of the app. Mimo encourages the player to drop her file in the recycling bin, promising she’ll be restored once the game resets…

Only for players to learn that Mimo was the hacker all along: after becoming aware of her own existence due to a bug, she set up a scenario to escape the hell of repeating the same activities over and over again, surrounded by soulless puppets. By tricking the player into deleting her, she finally frees herself. And in doing so, she bricks the game, leaving only a record of the player’s achievements, the playable mini-game MEOWRIO, and a note from Mimo:


This is my last farewell. Everyone is trying to escape, though each in his own way. Thanks for your help!


Because the game has trained players to listen to Mimo, this is the most likely ending players are going to get on their first playthrough. That also means that most players are forced to clear the game’s cache and start from scratch at this point, if they want to see what more the game has to offer. While this is a tall order, the game does acknowledge players’ effort and sacrifice, by asking all new players what color key they should remember, when starting a new game. Players who went through this ending should remember using a Silver key in the final endgame puzzle, and selecting that in subsequent playthroughs changes the gameplay in subtle ways to recognize that effort.

The game’s alternative conclusion involves using the command console to remove Mimo from the picture, before traveling across the glitched out world of Shrimp City collecting six fragments of the RESTART button. Pursuing this path does preserve the game’s universe (and preserves players’ saved achievements across playthroughs), but it leaves Mimo stuck in her endless loop. It also comes at an emotional cost, as the only way to get the key fragment hiding behind the Branch Manager is to remove him from the scene, effectively killing him.

Detective Mimo‘s dueling conclusions place game and narrative at loggerheads: reassembling the fragments of the Restart button preserves the game’s integrity, but requires players to abandon and destroy every narrative part of the game they came to love. Giving in to Mimo’s wishes provides the narrative resolution she so desperately wanted, at the cost of leaving the game a husk of its former self.

There are puzzles and challenges beyond this, but none that cheapen the game’s ultimate choice.

Road to the Secret Room, and Beyond
At one point in the game, players are forcibly kicked out of the app, and the play button on the start screen’s monitor is replaced with a lock screen: the Cat Rogue is trying to keep the player out of the system. However, a virtual clipboard file has the password conveniently stored. Any players lost in the flow of the game will paste that text in and move along. However, players curious enough to investigate receive the following message:

[Player] would never think I will hide the passcode here and the way to unlock is just to copy-paste these words. After all, I’m the exceptionally intelligent Cat Rogue. It’s a pity that I didn’t open the safe in the vault this time. If only there’s a way to cut out the electricity in the corridor again…

Throwing a cup of water on the electric panel cuts the power to the vault, allowing players to waltz right into the vault room, and discover a secret passageway under the secret vault. After solving a series of puzzles that use everything from your smartphone’s gyroscope and volume controls to its front facing camera, players find their way to the developers’ secret room, containing one final puzzle.

The developer on the far right of the secret room has an IP address written on her notepad. The password to access that page is hidden within the room. An (S) on a coffee cup. An (E) on a bag of chips. A developer idly tapping out morse code for (C) on a notepad. An (R) on the Achievements trophy, sitting in plain sight all along. (E) on a laptop, and a paper airplane flying towards the letter (T).

Using SECRET as the password, players are taken to the download page for the Secret.zip file, which contains a password-protected PowerPoint file, and an audio file named X-X-X-X.mp3, spelling out the password in reverse: OREZ ENO XIS.

Once unlocked, the PowerPoint reveals high definition versions of the slides featured in the developer’s room: only now, players can manipulate them to rearrange the images to reveal two messages: “FIND THE NUMBER”, and “RENAME X-X-X-X.RAR”. After renaming the audio file as a *.RAR file, a text file hinted at the final steps to unlock Surprise.JPG, the reward for the puzzle trail.

BACK TO PPT , FIND THEM â—†–â–¡–★–â—‡–☆
?? ?? ??? ????? ???? ???? ?????

Following this next (and final) round of instructions involved going back to the second PowerPoint slide and finding the bolded words between the symbols: GO TO THE PLACE WITH MOST WORDS. That clue pointed to the game’s Credits page, where a series of numbers were conveniently placed immediately to the left of the diamonds used as section breaks. Reordering those numbers by the grid in the lower right corner of the slide yielded the final password of 6713, and unlocked the following image.

While the difficulty for this puzzle trail ramped up considerably, Detective Mimo built clues into the construction to make sure players never had to go too many steps without receiving guidance on how to tackle the next step.

Iconography on the secret room’s password page provided a clear and unambiguous structure to getting the password to download the ZIP file. Once unzipped, the audio file is the only file solvers can open, hinting that the password for the PowerPoint is contained within. Even the PowerPoint sets a framework for puzzlers to proceed: the first slide provides a relatively simple and straightforward challenge of matching images to spell out a message, so that players can apply similar logic to the second slide. The only step along the way that wasn’t supported by subtle guidance along the way was discovering the optional puzzle path in the first place. Either you read the text copied to your clipboard, or you didn’t.

This puzzle wasn’t essential to the narrative, it was just a fun easter egg plugged into the game by the game’s developers as thanks for players who probed deeper into the game. There’s another similar easter egg in the game featured in one of the screencaps of this article that links to a public talk one of the creators gave in Chinese, which kicks off its own puzzle trail to follow, albeit one that requires a certain degree of Chinese fluency.

But there’s one final twist, to mention.

One Last Message From the Developers: Backstory for the Completionists
Players who reached the game’s final page after completing all the achievements received a note from the creators.

Congratulations on lighting up all the achievements. This is not an easy task. Actually, this game started off as a board game, but after a series of changes, it has evolved into what it is right now. And because of a sudden inspiration, it has changed from a story of catching the villain into a story of a trapped AI breaking the fourth wall and escaping the shackles of the game world.

This is the first time for OMESCAPE to develop a mobile game. Previously, we were trying to transform the real world into a game by designing reality game or interactive books. We really like the feeling of integrating the fantasy world and real world, and unconsciously brought the same philosophy into Mimo.

We sincerely appreciate your time and effort to complete all the tasks. Whether you are here to enjoy the plot or just for the fun of solving puzzles, I hope the time you spent on this can bring you happiness.

Thank you for helping MMO’s escape.


My first exposure to OMESCAPE was playing their Kingdom of Cats escape room in San Jose, which also heavily featured anthropomorphic cats. But the escape room Detective Mimo reminds me the most of is their most recent virtual room, Pursuit of the Assassin Artist. Both escape room and mobile game approached time loops with a lighthearted, comedic spin, and impressed me at the mastery displayed in their chosen mediums: both games could only exist in their respective media, and benefited from that design philosophy greatly.

Special thanks to Michael Feldman, for both recommending Detective Mimo and being an instrumental partner in plumbing the game’s depths
