## What it is
KorGE is a modern multiplatform game engine written entirely in Kotlin, built on top of the Korlibs multimedia stack. It targets JVM/Android, JS/WASM for the web, and native iOS and desktop via a Gradle plugin, with tooling like the KorGE Forge IDE, live-preview editor, and integrated debugger.

## Use cases
- build a 2d game in kotlin
- multiplatform game engine for android and ios
- make a web game with kotlin and webgl
- kotlin game engine with hot reloading
- develop games in intellij idea
- cross-platform desktop game development in kotlin

## When to choose
- you want to write games in 100% Kotlin across mobile, web, and desktop
- you value IntelliJ IDEA-based development, hot reloading, and live debugging
- you want a small-footprint engine with no external dependencies

## When to avoid
- you need AAA-grade 3D rendering or a large asset ecosystem like Unity or Godot
- you prefer engines with C# or visual scripting rather than Kotlin
- you need a very large community and marketplace of third-party plugins
