 1. **Engine Agnostic:** FelFlame has been designed to be rendering engine agnostic as long as the target rendering engine is written in Ruby. This means that this framework can be dropped into existing rendering engines such as [Ruby2D](http://www.ruby2d.com) or [DRGTK](https://dragonruby.org/toolkit/game) with little modifications.
 2. **Easily Extensible:** FelFlame has been designed such that extensions to its capabilities can be easily added. Extensions such as rendering engine wrappers, premade systems, premade components, etcetera can be easily coded and then distributed as gems.
