11 Every KYORA world is built by the game rather than hand-placed, and the systems that do that work sit underneath everything on the Gameplay page. World generation decides where the terrain, caves, greenery, resources, creatures and points of interest go, so no two players start in the same place. Environment design is the layer on top: the hand-authored intent that turns generated ground into a space worth digging through. Pugstorm has published three development updates covering this area, and the material below is drawn from what the team has stated publicly.

33 Pixels as the Base Unit
44  
55 KYORA is built around pixels, described by the team as tiny interactive units of terrain that can be shaped and manipulated with pixel-level precision. A player can carve twisting tunnels, hollow out a hideaway, or simply blow a section apart to see what happens. Terrain is portable as well as destructible: the developers have said a player can tear down a section of land, carry it somewhere else, and rebuild it however and wherever they like. Leaving the result messy is treated as a valid outcome rather than a mistake.

77 Noise and Terrain Authoring
88  
99 The team built a set of authoring tools during the development of Core Keeper and now uses those same tools for KYORA. At the core of them is noise, a mathematical pattern that mimics the randomness of natural terrain. For Core Keeper most of the world was produced by thresholding a single type of noise in various ways, which worked because tileset graphics carried much of the visual weight and a wall behaved the same in every direction.

1111 KYORA cannot rely on that. Tile density is far higher because the unit is a single pixel, there are no tileset graphics doing the heavy lifting, and every surface has to read correctly in a game where verticality matters. The team's answer was to extend its library of noise functions to ones that also return the gradient of the noise, in other words the direction a surface is facing. Knowing the facing direction is what lets the generator place grass on ground that points upward and rock formations on ceilings that point downward, and it is what allows far more surface detail than the earlier approach. Objects, creatures and points of interest are then placed on top of that base.

1313 Gravity and the Shape of the Land
1414  
1515 Gravity is the major structural difference between KYORA and the studio's earlier work, because every dynamic object wants to fall. Without care, the team has said, everything in the game ends up in a pile at the bottom. Generation is tuned against that outcome in several ways.

1818 The player-facing side of the same problem, including the glider, Gust Beetles and slingshrooms shown so far, is covered on Traversal and Movement.

2020 Designing a Destructible Space
2121  
2222 Environment design starts with sketches that set visual flow and atmosphere. Hazards and challenges are layered in during later passes, as a scene moves toward its more action-focused form. The stated aim is that environments are not only good to look at but are an active part of the adventure, both mechanically and narratively.
2323  
2424 The obvious tension is that a player can destroy anything the designers place. The team's answer is to build what it calls playgrounds: scenes designed on the assumption that players will blast through them, strip them for resources, and arrive from directions nobody laid out. Rather than protecting a fixed composition, the goal is that the space looks and plays well from any angle and offers several ways to read and interact with it. Detail is added after the playground exists rather than before.
2525  
2626 That framework is also used to give places an emotional register. The introductory biome is deliberately cozy and bright, with lush grass, rolling hills and soft background clouds, so that it feels safe and welcoming and gives more weight to the idea of leaving it. Individual areas are described on the Biomes page.

2829 In-Engine Tools
2930  
3031 How a finished area is produced varies from scene to scene. Some are generated by the studio's engine tools directly from an artist's silhouette, which lets the team see the scale of a space in-game almost immediately and spend the time saved on level design instead of redrawing. A cave shaped like a skull was shown as an example of this method. Other areas are assembled more modularly from what the artists call tilestamps, reusable set pieces that can be dropped in and then tweaked to fit the mood of a scene without redrawing anything from scratch.

3334 The team has said that these toolsets will be available in one form or another for players to try during Early Access, so that players have the same creative freedom the developers used to build the world. Exactly which tools ship, and in what form, has not been detailed.

3536 Reading the World
3637  
3738 Because a player can always dig a new path, routes are suggested rather than enforced. Resources are used as the signal: an open tunnel invites a player to walk straight through without ever swinging a pickaxe, but taking it means passing the valuable material buried alongside it. Materials mark the spaces worth excavating, and following them is meant to lead somewhere unexpected. The generator is also tuned to shape multiple routes and let interesting details peek in at the edge of the screen, which is where the pull to dig a little deeper is supposed to come from.

3940 Development Status
4041  
4142 Everything described here comes from development updates published between March and October 2025, and the team has repeatedly noted that the systems are still being iterated on. No generation parameters, world size, seed handling or tool interfaces have been published, and the studio has said it does not intend to detail the internals of the generator before the game is out.
