Welcome to Hex Curler!
======================
This game is based on Jeff Moore's Hex (http://www.1km1kt.net/rpg/hex).
Source code: gitlab.com/m-chrzan/hex-curler

How to Play
===========
If you're not using it already, run this line of bash to start playing:

c=; while clear; curl -c k -b k localhost:4567/$c; read c; [ $c ]; do :; done

You're about to start crawling through a dungeon, fighting monsters and finding
treasure. Your character has three attributes:
  - Health
  - Endurance
  - eXperience

After each move you'll be presented with a menu of options that could look
something like this:
  >[r]un away
  >[f]ight (-1 H, -1 E, 1 X)

Select a move by typing the highlighted letter and hitting enter (e.g. type r if
you want to [r]un away like a wuss).

Numbers in parentheses tell you how your attributes will be affected by taking
a given action.

To restart the game, run `rm k` to remove the cookie that stores your game state.
