The alley stinks of old rain and fresh lies. Finch squints through the gloom, trying to piece together what happened. Archie’s nose twitches—he already knows.

Welcome back to the dev diary series for Finch & Archie. This time, we’re diving into the beating heart of the game: the asymmetrical mechanic that puts one player in a trench coat and the other on four paws. Let’s talk about how we built it—and what we’ve learned along the way.

Why Man & Dog?

From the start, we were drawn to asymmetry. We didn’t just want two characters—we wanted two perspectives. Two ways of seeing the same world.

You and your partner aren’t meant to talk freely over voice chat. You’ve got an intentionally clunky, in-game comms system that forces you to learn how to share info in short bursts and weird phrases. It’s messy, inefficient, and sometimes hilarious. That’s the point.

The tension—and the fun—comes from struggling to translate your discoveries to your partner, even as you’re both trying to crack the same case. The mystery doesn’t just live in the world—it lives between you.

The result? High-stakes detective work, filtered through messy human (and canine) interpretation.

Their Skills, Their Stories

To make this work, each character needed their own distinct mechanics and narrative lens.

Archie, a sharp-nosed Pointer with more intuition than patience, sees the world through smell. His trail mechanic shows a clear path of travel from one location to another. At the start of a trail, you get a clue—something left behind that links to the person at the other end. The rest is on you to follow and piece together.

Finch, ever the classic noir detective, uses his magnifying glass to spot the small things: a torn scarf, a boot print, a smudged label. It’s how we show key evidence without overloading the player. He’s the classic sleuth, catching the details that others miss—but he can’t smell a lie like Archie can.

One sees the invisible. The other sees the overlooked.

The Puzzle of Partnership

Creating solo mechanics was easy. Making them work together was the challenge.

We’re constantly refining puzzles that require both players to interact with the same space, but from different angles—without leaving one player lost or idle. The goal is simple: both players should know what they’re doing, but not necessarily why it matters to the other.

The challenge has always been making both players feel essential. It’s not enough for one to be solving while the other watches. We wanted both to understand their own piece of the puzzle, then struggle (and laugh) as they try to combine them.

Sometimes that works beautifully. Other times, one partner ends up wildly guessing while the other shrugs helplessly. We're still refining that balance—but that's the fun of it.

One of our favourite examples is our item mechanic. You might find a character who refuses to help without a bribe—or a very specific object. Problem is, you don’t have it… but your partner might.

Suddenly, you’re yelling across the room, “Rat need smoke stick!” and hoping your partner can figure out what that means before they can move on. 

It ties the environment, NPCs, and co-op communication into one very loud (and hilarious) moment.

What We’ve Learned

We started with a serious noir murder mystery. Gritty. Grimy. Moody. But somewhere along the way, something unexpected happened: the characters came to life—and they were funny.

The more we wrote, the more they joked. The more they joked, the more we leaned in. They started driving the tone. We followed. The noir is still there, but the game feels alive now—like two real partners who can’t help but bicker through the job.

We’ve also learned that players will always surprise you. Some stumble into the solution, others brute-force their way through. But if they’re having fun, we’ve done our job.

Evolving the Partnership

The heart of Finch & Archie is the partnership itself. Not just in the story, but in the way you play.

At the beginning, Finch and Archie are uneasy allies—just doing the job. But as the story unfolds, their relationship deepens, and their cooperation tightens. That narrative arc mirrors the ludonarrative one: players, too, begin unsure of how to work together—but grow more intuitive, more connected, as they go.

That bond—on screen and off—is what the game is really about.

That’s all for now. We’ve still got plenty of puzzles to tweak and trails to follow, but this mechanic is the soul of the game.
