winter themed roguelike for you to practice Java

[Eben]

I put up a lab I constructed from practicing all levels of Java programming, from basic control statements to threading. It features a minimally implemented roguelike so you start with a working game and expand it in ways outlined in an instruction sheet. The practice areas are decoupled, so you can do just the parts you want rather than having to go through a specific order of things.
