# Bird's-eye view of a PuzzleScript file

A puzzlescript file is divided into 8 sections:

## Legend

This section has two purposes. Firstly, it's a place where you can set up single-character names for things so that you can type them in levels:

    P = Player
    . = Background
    # = Wall
    * = Crate
    O = Target
    @ = Crate and Target

There is another purpose, and this is to define properties of objects that you can refer to in rules and elsewhere:

    Flying = Bat or Bird
    Obstacle = Wall or Lava or Water
