echo

Integrates seamlessly with multiple Haxe frameworks like Heaps, OpenFL, and Kha via compiler flags, avoiding tight coupling and allowing reuse across projects.

Uses Separating Axis Theorem (SAT) for reliable collision detection between rectangles, circles, and convex polygons, ensuring precise physics interactions.

Features physics state management with undo/redo functionality, a rare inclusion that simplifies debugging and state reverts in simulations.

Implements a quadtree for broadphase collision querying, optimizing performance in dense scenes by reducing unnecessary checks.

Provides on_move and on_rotate callbacks and a build macro for adding custom fields to bodies, streamlining synchronization with game entities without boilerplate.
