Best Fiends underwent a complete engine transformation to modernize their live game. The team rebuilt their matching engine as a deterministic, pure C# ECS-like system decoupled from Unity's rendering layer, enabling reuse across components. They created a standalone level editor with WYSIWYG capabilities using Unity UI tools, allowing designers to work without touching the base game or version control. The project involved rebuilding 10,000 levels, implementing comprehensive unit testing with Unity Test Framework, and replacing baked-in levels with a cloud-based content delivery system for faster updates.
