Announcing Limn Engine — A Lightweight 2D Game Framework for the Browser

Announcing Limn Engine I'm excited to launch Limn Engine — a lightweight, zero-dependency HTML5 Canvas game framework for the browser. No npm install. No build step. No bloated dependency tree. Drop in a single script and start making 2D games. The Core Idea: Display + Component Limn Engine is built around two classes that cover 90% of what you need in a 2D game: Display — The Game Shell A singleton Display class that manages the canvas, runs the game loop, handles keyboard and mouse input, controls the camera, and manages scenes. Setting up a game is a one-liner: const display = new Display (); display . start ( 800 , 600 ); Let me try creating it step by step . Component — Every Object in Your Game A unified Component class that combines position, size, color/image, velocity, physics, and collision detection. No separate "Sprite" and "Body" classes — one object does it all. const player = new Component ( 40 , 40 , " blue " , 100 , 100 ); Components support three modes: Rectangle — solid color shapes for rapid prototyping Image — loaded from spritesheets or single image files Text — the Tctxt subclass for text elements with backgrounds, padding, and alignment Key Features Dual-Canvas High-Performance Rendering Call display.perform() to activate dual-canvas mode. Static backgrounds and tilemaps are drawn once to an offscreen buffer, then composited as a single drawImage() call per frame. This dramatically reduces draw calls and improves frame rates for complex scenes. display . perform (); display . start ( 800 , 600 ); Tilemap Levels Define game worlds as 2D arrays and initialize the tilemap engine with one call. Supports dynamic tile placement during gameplay — great for destructible environments and breakable blocks. display . map = [ [ 1 , 1 , 1 , 1 , 1 ], [ 1 , 0 , 0 , 0 , 1 ], [ 1 , 0 , 9 , 0 , 1 ], [ 1 , 0 , 0 , 0 , 1 ], [ 1 , 1 , 1 , 1 , 1 ] ]; display . tileMap (); Sprite & AnimatedSprite Load horizontal spritesheets and define named animation clips (idle,
