## What it is
doukutsu-rs is a faithful open-source reimplementation of the Cave Story (Doukutsu Monogatari) game engine written in Rust. It supports original freeware, Cave Story+, and Nintendo Switch data files while adding modern quality-of-life improvements like smooth motion, flexible resolution, and cutscene skipping.

## Use cases
- play Cave Story with modern quality-of-life improvements
- run Cave Story on Linux, macOS, Windows, or Android
- play Cave Story with smooth motion on high refresh rate displays
- use one executable with freeware, Cave Story+, or Switch game data
- skip cutscenes while playing Cave Story
- play Cave Story with enhanced lighting effects

## When to choose
- you want to play Cave Story natively on modern platforms with widescreen and high-refresh-rate support
- you need a single engine that works with freeware, Cave Story+, or Switch data files
- you want an open-source, actively maintained Cave Story engine

## When to avoid
- you don't own or can't obtain Cave Story data files, which are required and not included
- you want to play the original 2004 engine exactly as-is without enhancements
- you need a general-purpose game engine for building your own games
