# Overview
defGameEngine is a lightweight, cross-platform (Windows, Linux, MacOS) 2D game engine designed for simplicity and ease of use. It provides essential tools for rendering graphics and handling input. The engine supports both desktop (via GLFW) and web (via Emscripten) platforms.
# Features
- Cross-Platform: supports Windows, Linux, macOS, and web browsers.
- 2D Rendering: draw shapes, sprites, textures and text with various blending modes.
- Input handling: keyboard, mouse and touch input (web) support.
- Sprite & texture management: load, manipulate and render fully rotated and scaled images.
- Layers: organise rendering into layers with custom shaders.
