## Description

Excalibur Dev Tools is a powerful Chrome extension designed specifically for developers using the Excalibur.js game engine. It offers a comprehensive set of utilities to help you explore and debug your games with ease.

With this tool, you can quickly identify the Excalibur version your game is running, toggle debug drawing on or off, and deeply inspect game Actors and Entities. It also allows you to remove entities dynamically and view all the scenes present in your game. Additionally, performance metrics like FPS, frame time, frame budget, and draw/update times are displayed over time to help you optimize your game. For detailed testing, switch to the test clock mode and step through your game frame by frame.

Whether you’re developing a complex game or refining gameplay mechanics, Excalibur Dev Tools provides indispensable debugging features to enhance your development workflow.
