is not a port or a compromise—it’s a first-class citizen in the 2D animation world. Its skeletal workflow saves enormous time compared to traditional sprite sheets: a 30-frame walk cycle can be created with 5 key poses and automatically interpolated. With native Apple Silicon performance, tight SpriteKit/Metal integration, and a robust runtime ecosystem, Spine remains the gold standard for 2D game animation on macOS.
