Installing
On Unix:
$ make check (optional)
$ su
Password: <enter it here>
# make install
Then run 'angrydd'. Alternately, check the website to see if a package is available for your system.
On Windows, simply unzipping the program and double-clicking 'angrydd.py' or 'angrydd.exe' should run it, if you have Python and Pygame installed. (Don't ask me for help getting it running on Windows.)
Playing
Angry, Drunken Dwarves is much like many other falling block games, so you can probably jump right in and play. The basic goal of the game is to combine gems of the same color into large crystals, then break them, dropping more gems on your opponent.
Although the game is much more fun with gamepads, it can be played with the keyboard.

Character Selection
When you play two player games, Angry, Drunken Dwarves will ask you to pick a character to play. Besides the obvious importance of things like beard length, each character also has a 6x4 "drop gem pattern". This is the pattern by which gems are dropped onto an opponent's side. The more irregular the pattern, the tougher it is to prepare for. However, if the pattern is too random, your attack power will be lessened slightly. The converse is also true: If your pattern is very regular, you will drop more gems to compensate.
