2048 is a command-line implementation of the hacker-pop-culture boardgame by the same name. The goal of the game is to combine tiles of the same number until one creates the "2048" tile. The entire board may be moved by using either "wasd" (standard gaming movement keys) or "hjkl" (vim keys). Use Ctrl+C (SIGINT) to exit. Use "?" to display a help message.
