The Level File Format
=====================

Introduction
------------

This file format is used to specify level maps in tile-based 2D games.

Level Data
~~~~~~~~~~

The level data immediately follows the file header. Essentially, this encodes
*(width * height)* unsigned 8 bit values that are the 1-based tile number.
