Reboot's In-Depth High Velocity Library

Ridhvl is a library designed to provide quick shortcuts and templates for game jams such as the Ludum Dare and MiniLD.

Admittedly, this library was designed with my own personal use in mind. However, pull requests that provide helpful and logical additions will be accepted.

Ridhvl requires Lwjgl 2 and slick-util to function.
