# Go Raycasting Engine

This is a simple raycasting engine implemented in Go using SDL2. It simulates a 3D environment similar to the rendering technique used in classic games like Wolfenstein 3D.

## Features

- Real-time 3D projection with raycasting
- Movement and rotation controls
- Multiple wall textures loaded from PNG files
- Text rendering (e.g., FPS counter or debug text)
- SDL2 rendering (no OpenGL or GPU shaders required)
