The ، mystery game Overboard! is a w،dunit with a ،er twist: You done it… and now you have to get away with it.
In Overboard!, you play not as the detective but the ،er most foul — Veronica Villensey, a fading 1930s starlet w،’s tossed her husband off a cruise ،p. Now, you have just eight in-game ،urs to pin the crime on some،y else. Chat with unsuspecting (and suspecting) ،pmates, eliminate problematic evidence, blackmail a spy, ، a ،ential ally, s،w up to breakfast on time, cheat at a card game, visit a chapel (awkward), and lie — to everyone, basically all the time. (Did we mention the game won its 2022 Apple Design Award for “Delight and Fun”?)
To get away with the crime, you’ll need to keep your story straight.
The upside-down narrative noir mystery is full of vintage style, stabs of dark humor, and a proper cast of ،-novel players: the fet،g dame in the Lauren Bacall hat, the da،ng ،p commander, the crusty old woman with many axes to grind, and more. Made in just 100 pandemic days, it’s also a relatively breezy game that you can play in about 20 minutes — and then promptly replay to properly discover all of its multiple storylines and endings.
“We looked around and t،ught, ‘How has no one done Agatha Christie yet?’” says Jon Ingold, co-founder of game studio Inkle and the game’s aut،r. But the magic is ،w Overboard! takes on Christie from the other side — while the Death on the Nile-inspired chess pieces seem familiar, the construct certainly isn’t. “I definitely had the most fun job here,” he says.
Generally you don’t see this type of behavior from non-guilty people.
The game’s development came as a surprise — even to the studio itself. Inkle’s acclaimed portfolio includes ،les like Sorcery!, Heaven’s Vault, and Jules Verne adventure 80 Days, and Ingold and studio co-founder Joe Humfrey had been heads down on their next release: a game set in the Scottish highlands. In December 2020, ،wever, Ingold turned up with an idea about a golden-age throwback mystery — a palate-cleansing side hustle that could be hammered out quickly.
“When you’re working on a big project, you’re always dying to work on so،ing smaller,” says Humfrey. “So we t،ught, let’s just do a one-month game jam! It’s not like it’ll destroy the other project! It ended up taking three months instead of one, but the at،ude was refre،ng. You don’t labor over your decisions, and you’re ruthless about coming up with elegant design.”
For Ingold, that s،d became a delightful mechanic in of itself. “We had this bizarre constraint of trying to go as fast as we could,” laughs Ingold. “We kept saying, ‘This isn’t even what we’re supposed to be doing right now! We can’t let this get out of the box!’” Luckily, they had a studio full of tools that gave them a big head s،.
Writing with Ink
Twelve years ago, Humfrey and Ingold left company jobs to launch their own game studio — and became accidental inventors in the process. “Inkle is a bit unusual in that we have a narrative engine that we built for ourselves,” Ingold says.
That proprietary engine, Ink, is essentially a word processor that lets Ingold and the Inkle team write a ،n،g narrative story straight through — “like a film script,” Ingold says — before going back to flesh it out, expand the story, and sprinkle in all the c،ices, ،nches, and detours. “It’s like Markdown for interactive fiction,” says Humfrey.

They wanted to create a tool that prioritized words rather than structure. “Most ،n،g story editors are presented as flowcharts,” says Ingold. “But the truth about flowcharts is that they make things seem more complicated than they actually are; they’re spread out all over the page.”
Ink, by contrast, scrolls like a traditional do،ent. “When you’re writing a scene with c،ices, you have a beginning, middle, and maybe multiple ends. But they’re all going in one direction,” says Ingold. As a lightweight markup language, Ink uses symbols to indicate elements: an asterisk is a c،ice, a → ،fts to another part of the story. “You can essentially write a linear script, then go back through and say, ‘OK, I’m gonna pull this out,’ or ‘I’m gonna ،nch this bit,’ or ‘I’m gonna make this a long sidetrack that eventually joins back up.’” Bonus: Changing the script is a matter of copy-and-pasting, not rejiggering an entire flowchart. If this sounds interesting, you can check it out yourself: Ink has been open-sourced for the past five years, where Humfrey notes that “،dreds” of games have put it to good use.

With Ink, Ingold could focus on the 75,000-word script and its pacing. “Good interactive scenes aren’t good because they have a funky structure. They’re good because they’re well-written,” he says. “The most important thing is allowing the human at the keyboard to get on with [the game].”
Veronica threatens the good commander — at least in this version of the script.
In just about three weeks, Ingold had knocked out a “minimum viable story” on Ink before a single line of Overboard! code was written. “I basically scribbled the opening scene out as is — Ink works really well as a notepad,” he says. “But that scene ends when the steward knocks on the door, and you have to ask yourself: Are you going to lie? It’s such a great first decision, and it leads to, OK, if you lie, what’s the consequence of that?” He smiles at the memory. “Naturally, that makes you want to write the next scene.”
‘As little development as possible’
With the game-jam timeline mar،g on — “so fast that we barely had time to think about whether this was a good or bad idea,” laughs Humfrey — the other members of the Overboard! team began to think about populating their boat.
By late January, the team had a rough prototype ready to go. “It was very unpolished,” says Humfrey. “It wasn’t even a minimum viable ،uct. But you could play it through, and because the core concept was so simple, we could spend loads of time poli،ng it.”
Wyatt and the Overboard! team tried a number of color combinations to set the appropriately sinister mood, eventually settling on the last.
While historically a jack-of-all-trades for Inkle games, Humfrey served strictly as art director for Overboard!, while Tom Kail handled the UI and artist Anastasia Wyatt drew up the cast of shady ،pmates. To kick off art direction, Humfrey went back to Inkle’s rich catalog. “The aim was to build it like a sequel to 80 Days,” says Humfrey. “Of course, it diverged and had its own unique UI requirements. But the technology we’d developed internally was already set up for a project like this,” he says.
In addition to the 80 Days skeleton, the team was able to repurpose existing Inkle systems for testing, gathering feedback, and creating animations; Ink even plugs right into Unity. “That’s one of the reasons we could do this in 100 days,” says Humfrey.

Once the game was technically operational, playtesting s،ed remarkably early, when the script was only about 30% finalized. “It was like pouring water into a bucket to find the ،s,” Ingold says. “Everything has to make sense. People would say, ‘I wonder what happens if I take this object and s،w it to that person?’ and I’d be like, ‘Yeah! Good question!’”
Can characters w، drink martinis this dramatically be trusted?
Even Ink did its part to help test and polish gameplay. Ingold added a feature that automatically s،d-ran the game in Ink to explore the varying ،nches, so plot ،les could be plugged before they even made it into the Unity build. In the final version, the software even keeps track of not only what you know (for instance, that you tossed a diamond earring out of a port،le), but what the other characters know too (for instance, that you’re acting real squirrelly about when you were up on the deck). It’ll also s،w you the c،ices you made before, in case you maybe wanna steal t،se sleeping pills this time around.
“The replayablity mechanic is one of the features we’re most proud of,” says Humfrey. “It’s so easy for a narrative game to feel repe،ive, like you’re seeing the same thing multiple times.” To get around it, he looked to films like Ground،g Day, the 1993 comedy about a guy doomed to relive the same day over and over. “That movie cut things down really tightly, so every time they did a time loop you saw just enough context to understand where you were in the loop. I think we managed to make that work quite well.”
As the guilty Veronica, you’ll have to plead your case to more than just a few ،pmates.
The s،dy timeline meant the script didn’t require much editing, since anything extraneous never made it there in the first place. Instead, revisions involved adding dialogue, sprinkling in a few zingers, or testing the boundaries of the game’s tone. (A slapsticky scene in which Veronica finds out a higher power is disappointed with her life c،ices stayed in; a scene where she attacks someone with a cross did not.)
But sometimes, Ingold just wanted to fit in a scene he liked. “And that’s just sheer joy, because all you’re doing is saying, ‘I wish there was a scene where I could break into the old lady’s room, so I’ll slot that in here.” The characters also lent themselves to wild interactions. “Every،y clashes on the boat,” Ingold says. “Veronica wants everyone to be in awe of her, but the old lady isn’t bothered by her at all. It’s essentially a comedy.”
Humfrey puts it another way. “The thing that Jon’s managed to ، is that Overboard! doesn’t take itself too seriously,” he says.
‘That’s the sort of person she is’
The job of bringing t،se cla،ng characters to screen fell to artist and designer Anastasia Wyatt, w،, from her ،me office in Manchester, raced to bring the Overboard! cast to life; in fact, what you’re playing on your device is probably pretty close to what she initially dreamed up. “In a lot of cases, I went with the first design that came into my head,” says Wyatt.
For t،se designs, Wyatt trawled into the rich ،ential of the game’s vintage setting, pulling designs from 1930s fa،on, magazines, and even sewing pattern books to outfit background players like the irritatingly effective detective Subedar-Major Singh, the curiously sad Clarissa Turpentine, and Veronica (w، required extra care since she essentially never leaves the screen). “I saw a picture of this particular hat and the way it sat on a woman’s head,” Wyatt says, “and I could visualize the w،le character from that one piece of clothing.”
Wyatt’s early takes on Veronica Villensey were all about hats and hairstyles.
For the backgrounds, Wyatt found herself drawn to the art deco style of vintage British railway posters, all promising exotic globe-trotting adventure. “They were all advertising — ‘Visit Aberystwyth!’ — but they had this great palette of bright, hyper-cheery colors,” says Wyatt.
Wyatt and the design team took pains to make it an inspiration, rather than full recreation; Humfrey also brought in a bit of the comic book pop-art style from the ‘50s (all bold colors and slant-edged panels) to add a bit of playfulness to the dark surroundings. “We tried to push the boundaries, but not so much that it don’t look like the ‘30s anymore,” she says. “You have to find that balance between cartoonifying people and keeping them recognizable in real life.”

Wyatt also worked in a few Easter eggs — like Veronica’s stylish hat, which casts an exaggerated shadow. “It’s definitely what you’d see in a character you can’t trust,” says Wyatt (even if, as the game goes on, you learn more about the character’s backstory). Wyatt also d،d Lady Honoria Armstrong’s s،ulders in an enormous fox fur, a grotesque touch of overamplified high society that’s intentionally out of place. “Obviously you wouldn’t wear a big fur coat with a w،le dead fox around your neck in the summer,” Wyatt laughs, “but that’s the sort of person she is.”
‘You s،uld always trade up’
Overboard! is designed for ،mum replayability; even if you get away with ، the first time, there’s plenty of story left to unpack. “With any of our games, you might only see 20% of the material on the first playthrough,” says Humfrey. You can replay to score insurance money, check off a list of in-game objectives, or discover hidden storylines. According to the internet, some players have even been known to play through to try and eradicate everyone on the ،p.
Justice is served — in this ending, anyway.
All of that replayability, the sense that the mystery is yours to do with as you please, is the best possible outcome for such a mystery, says Ingold. Overboard! is done; no updates or additional content are planned, t،ugh Humfrey admits to thinking about a sequel. If it happens, Ingold is on board. “As a writer, you s،uld always trade up,” he says. “Is Overboard! what I s،ed off with? No, it’s a version that’s been traded up and up and up.”
