Playdate gets an ambitious first person 3D game with KATAVATIS

The Playdate doesn’t look like a machine built for 3D games. Its screen is tiny. It only displays black and white. There’s no dedicated graphics hardware, and the controls are far simpler than anything you’d find on a modern console. That’s exactly why KATAVATIS is so interesting. The in-development first-person game, created by Cristina Ramos, is turning Panic’s compact handheld into an unexpected platform for 3D exploration. Recent footage shows outdoor environments filled with rooftops, towers, platforms and exposed architectural structures. It’s a major step beyond the enclosed rooms and narrow corridors that usually make early software-rendered 3D easier to manage. This isn’t just a visual trick, either. The game is beginning to look like a real, explorable space.

A renderer made specifically for Playdate

KATAVATIS doesn’t lean on hidden 3D hardware. There isn’t any. Instead, the game uses a custom software renderer built around the Playdate’s ARM processor and its 400 by 240-pixel one-bit display. The engine has to calculate geometry, clip surfaces and draw the scene entirely through software, all while keeping performance steady enough for first-person movement. That’s a tough job.

The screen creates its own problems, too. On a colour display, developers can separate objects with lighting, materials and subtle shifts in tone. Playdate offers black pixels, white pixels and carefully placed dithering. Use too much detail and the picture turns into visual noise. Use too little and the world becomes flat or confusing.

KATAVATIS handles this by keeping its geometry readable. Buildings have strong shapes. Edges are clear. Dithering adds depth without smothering the scene. The renderer doesn’t try to copy what a modern graphics card would do. It works with the hardware instead. That’s the smarter approach.

Old-school tools meet custom technology

The game’s development pipeline has roots in early PC level design. Its environments are built with brush-based geometry in TrenchBroom, a level editor closely associated with Quake-style mapping. Developers use simple solid shapes to create rooms, platforms, walls and larger structures, then export that geometry into a custom format designed for the engine. It’s an efficient setup.

There’s no need to force a large modern toolchain onto a handheld that was never meant to support one. The editor handles the practical level-building work, while the custom engine takes care of rendering those spaces within Playdate’s limits. That combination also suits the game’s visual style. Large surfaces and sharp structural forms remain readable on the small screen. Fine details would probably disappear anyway.

Outdoor levels change the challenge

Interior 3D environments give developers plenty of ways to control performance. Walls block the player’s view. Corridors limit how much geometry appears on screen. Doors and corners hide sections of the map that don’t need to be rendered yet. Outdoor levels remove much of that safety net.

From a rooftop, the player might see platforms, buildings and structures stretching across a large part of the environment. The engine has to process more surfaces at once, and the game still needs to maintain a clear picture. Distance is another issue.

A one-bit display can’t rely on colour fades or atmospheric effects to show that one object sits far behind another. The scene has to create depth through size, overlap, contrast and pattern density. Get that balance wrong and everything blends together. Get it right and the tiny screen suddenly feels much bigger.

The comparison with Mirror’s Edge makes sense here. KATAVATIS doesn’t copy its bright colour palette, but both games use clean architecture to guide movement and make spaces easy to read. Rooftops, ledges and platforms stand out because their shapes do the work.

It needs to play well, not just look clever

Rendering polygons on Playdate is impressive, but that alone wouldn’t make KATAVATIS a convincing game. First-person movement has to feel stable. Collision detection needs to behave properly. Players must understand where they can walk, jump or climb. They also need to judge distance without second-guessing every platform. That gets harder in large exterior areas.

KATAVATIS is planned as an underwater first-person exploration game with puzzle-platforming and Metroidvania elements. That means the world can’t just be a sequence of disconnected technical demonstrations. It needs linked areas, vertical routes and locations that stay understandable when approached from different angles. The renderer has to support all of that. So does the level design.

Playdate’s limits are shaping the game

KATAVATIS shows why hardware specifications only tell part of the story. On paper, Playdate isn’t an obvious 3D system. But software designed around its exact limitations can achieve far more than a direct comparison with modern hardware might suggest. The key is focus.

The renderer fits the processor. The art fits the display. The level-building tools fit the geometry. Each part supports the others instead of fighting the machine. The outdoor environments are still part of a developing project, and the game may continue to change. Even so, they already prove something useful. Playdate’s 3D ceiling is higher than it looks.
