Open source · 2.5D first · Real 3D when you need it

Build worlds
with depth.

Parlyn is a free and open-source game engine built around modern 2.5D development — combining sprites, billboards, layered scenes, lighting and true 3D geometry in one coherent workflow.

A DIFFERENT STARTING POINT

2.5D is not a fallback.
It is the foundation.

Parlyn does not treat 2.5D as “fake 3D” or a secondary editor mode. It treats depth, layered imagery and real geometry as equal building blocks — so small teams can create rich worlds without carrying the production cost of full 3D everywhere.

BUILT AROUND THE WORK

Less engine wrestling.
More world building.

Parlyn owns its scene graph and project format while keeping the renderer behind a clean abstraction. That means the editor can evolve without welding your project to one graphics backend forever.

CORE

Depth-native 2.5D

Sprites, billboards, layered depth, 3D lights and geometry coexist inside one scene instead of living in separate worlds.

◇
SCENES

Simple node model

First-class nodes for 2.5D and 3D keep scenes understandable, inspectable and easy to extend.

</>
OPEN

Plain project data

Readable project and scene files keep your work transparent instead of hiding it inside opaque editor formats.

⬡
ASSETS

Open asset pipeline

Common formats first: images, glTF/GLB, OBJ and audio form the basis for a practical, vendor-neutral workflow.

◐
RENDERER

Backend abstraction

THREE.js powers the viewport today, while Parlyn's higher-level concepts remain independent from it.

MIX WHAT MAKES SENSE

A scene can be
whatever it needs to be.

A real 3D floor. 3D architecture. Illuminated 2.5D characters. Billboard vegetation. Parallax backgrounds. Particles and atmosphere. Parlyn is being designed to give you useful pieces without dictating the recipe.

  • Real depth and perspective
  • 2.5D characters and environments
  • 3D geometry in the same scene
  • Modern lighting and material workflows
