Some games tease their hand. Moves of the Diamond Hand lays its cards on the table within the first few minutes: you’re going to have a lot of strange conversations, and you’re going to roll a lot of dice. Buy into that pitch and you’re rewarded with one of the most genuinely inventive roleplaying experiences to surface in years — even if the game is far from done.
This is an Early Access title from musician and game designer Cosmo D, available now on PC, macOS, and SteamOS. That last platform matters: it runs on the Steam Deck, which is where our source spent their time with it, and the handheld feels like a natural home for a game this unhurried and exploratory.
Aesthetically, it’s a deliberate throwback. Moves of the Diamond Hand looks and plays like a first-person RPG or immersive sim from the early-to-mid 2000s — the kind of era when polygons were sparse and atmosphere did the heavy lifting. Environments here are grimy, stark, and blocky, leaning into that low-fi texture rather than apologizing for it. It’s a look that signals intent: this is a game built around mood and curiosity, not photorealism.
The dice are the engine. Rather than hiding its mechanics behind menus, the game foregrounds the roll, turning chance into a tactile, ever-present part of how you move through its world and its conversations. That makes every interaction feel slightly precarious — a deliberate jolt of unpredictability woven into the storytelling.
What you should know going in is that this is unfinished by design. Early Access means you’re stepping into a work in progress, and Cosmo D has been clear that the game’s many mysteries won’t be fully resolved until 2027. That’s the date on the calendar — players who jump in now are signing up for a slow reveal rather than a complete arc.
For some that’s a dealbreaker; for others it’s the whole appeal. There’s a particular pleasure in inhabiting a strange, half-formed world and watching it fill in over time, especially when the underlying vision is this distinctive. Cosmo D’s background as a musician bleeds into the texture of the thing, and the result is less a conventional RPG than an interactive headspace you wander around in.
If you want polish, certainty, and a tidy ending, the timeline alone may give you pause. But if the phrase “irresistibly weird dice-based RPG” makes you lean forward rather than back, Moves of the Diamond Hand is exactly the kind of oddball, creator-driven project that the indie scene exists to produce. Roll well.
