## What it is
Murder is a pixel art game engine built on top of FNA using an entity-component-system (ECS) architecture via the Bang framework. It includes an integrated editor as a separate project within your game solution, targeting Linux, macOS, Windows, and Steam Deck with .NET 8.

## Use cases
- build a 2D pixel art game in C#
- make a game with an ECS architecture
- develop games for Steam Deck
- create a game jam project quickly
- edit game levels and entities inside my own project

## When to choose
- you want a C# pixel art engine on FNA with ECS
- you prefer editor code living inside your own project like MonoGame/FNA workflows

## When to avoid
- you need a stable, mature engine with NuGet packages
- you need console platform support today
- you dislike frequent breaking changes

## Facets
- artifact type: framework
- maturity: active
- function: game-engine, gui
- domain: cross-platform
- platform: windows, cross-platform
- tags: ecs, pixel-art, fna, csharp, 2d, editor, game-development, linux, macos, desktop
