Platformer.js

Platformer.js is a robust, modular game engine designed specifically for 2D platformers. It abstracts complex game loop mechanics, physics calculations, and collision detection into a clean, easy-to-use API.

Leveraging PixiJS for high-speed rendering, it ensures smooth 60fps gameplay even with many entities on screen. The engine includes a component-based entity system, making it easy to extend behavior for new enemies, items, or player abilities.
