## What it is
A Unity 2D character controller component similar to Unity's built-in CharacterController, providing a move method with raycast-based collision handling for 2D platformers. It includes a demo scene and supports features like one-way platforms and collision events.

## Use cases
- build a 2D platformer character controller in Unity
- handle player movement and collision with platforms
- implement one-way platforms in a 2D game
- create solid player movement for enemies and NPCs
- detect collisions during character movement

## When to choose
- you are making a 2D platformer or action game in Unity
- you want a lightweight, code-driven alternative to Unity's built-in CharacterController for 2D
- you need reliable raycast-based collision for a 2D character

## When to avoid
- you are building a 3D game
- you need a commercially licensed asset (it uses CC BY-NC-SA 3.0)
- you need an actively maintained solution with recent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: game-engine, simulation
- domain: gaming-tools
- platform: game-engine, cross-platform
- tags: unity, 2d, character-controller, physics, collision-detection, platformer, game-development
