## What it is
LDtk (Level Designer Toolkit) is a free, open-source 2D level editor built with Haxe and Electron, created by the director of Dead Cells. It offers a user-friendly interface for designing game levels with auto-rendering, customizable entities, and simple JSON/PNG export for game engines.

## Use cases
- design 2D platformer game levels
- create top-down game maps with tilesets
- define game entities like enemies and triggers with custom properties
- export level data as JSON and PNGs for a game engine
- import Aseprite files directly as tilesets
- organize levels into worlds with grid-vania or free layouts

## When to choose
- you are building a 2D platformer or top-down game and need a dedicated level editor
- you want a free, modern alternative to Tiled with a polished UI
- you need simple JSON/PNG export that is easy to import into any engine
- you use Aseprite for pixel art and want live-reloading tilesets

## When to avoid
- you need a 3D level editor
- you require isometric perspective support
- you need a headless or scriptable level-generation tool rather than a GUI editor
