## What it is
DOTween is a fast, type-safe C# tween/animation engine for Unity, evolved from HOTween v2. It animates numeric and non-numeric values (transforms, materials, strings) via fluent shortcut extensions like transform.DOMove(), with sequences, loops, callbacks, and modular Unity system support.

## Use cases
- animate a Unity transform to a position over time
- tween UI elements in a Unity game
- create sequenced animation chains in Unity
- scale or fade game objects with easing
- animate material properties and strings in Unity
- avoid GC allocations when tweening in games

## When to choose
- you are building a Unity game and need performant, type-safe tweening
- you want a mature, widely used animation library with extensive documentation
- you need to tween almost any value type with sequences and callbacks

## When to avoid
- you are not using Unity or a C# game engine
- you need skeletal or timeline-based animation rather than value tweening
- your project requires a permissive open-source license (license is custom/restricted)
