WHAT:
  
  So, uh, there's a bunch of penguins on an iceberg in Antarctica. You have
  been selected to catch them so they can be shipped to Finland, where they
  are essential to a secret plot for world domination.

  In order to trap the penguins, you'll need to break the iceberg into small
  chunks. (They're afraid of water, for no apparent reason. Ah well. "The
  Matrix" had more plot holes than this, and it still was a hit.) You do
  this by melting lines in the ice with Special High-Tech GNU Tools.

  If a penguin hits a line in progress, however, it vanishes with a loud
  noise, and you lose a life. (Yes, a life. This story is really breaking
  down, isn't it? But never fear -- I'll keep going until it's completely
  dead.)

  Once 80% or more of the iceberg is gone, the remaining chunks are small
  enough for shipping. Of course, if you manage to get rid of more than
  that, you'll save on postage, thus earning you exponential amounts of Geek
  Cred (a.k.a. "score").

  After you ship off one batch of penguins, it's time to move on to the
  next. Each subsequent 'berg will have one more penguin, and you'll have
  one more life. This will continue until you lose, or until you exceed
  level one hundred or so, which Ain't Gonna Happen. 

  Of course, this is an urgent mission, so you'll be penalized if you're
  slow -- every second or so, your score drops down by one. But don't worry,
  I'm not completely cruel, so any points you earn on one level are yours to
  keep forever, no matter how long you take on subsequent icebergs.

  As far as I can tell, this makes no narrative sense whatsoever, so at this
  point, I declare the backstory / game metaphor completely collapsed. Just
  go play.


HOW:

  The left mouse button starts drawing lines; the right (and/or middle)
  button toggles between making vertical and horizontal lines.  Note that
  left clicking actually starts *two* lines: either up and down or left and
  right. (This will make plenty of sense when you're actually playing.) If
  one of these lines is hit before it reaches the edge of the iceberg,
  you'll lose a life. If both are hit, you'll lose two lives.

  As a tiny bit of grace, if you click directly on a penguin, it'll say
  "Ouch" and nothing else will happen.

  Once a line is completed, any area containing no penguins is cleared.
  Falls into the ocean, so to speak. Once 80% has been cleared, the level is
  complete. However, you get an exponential bonus for every percentage point
  above that, so you want to try to make your last line suddenly clear a
  huge chunk of ice. (Again, this will make sense once you've played for a
  while.) Oh, and you also get a (much smaller) bonus for having lives left
  over at the end of a level.

  Taking a long time on a level doesn't affect these bonuses, but it can
  chip away at your score, so you have to balance the time it takes to set
  up a situation where you can clear 99% of the iceberg against the bonus
  you'll get for doing so.

  Having trouble? A hint: it's useful to make traps by intentionally letting
  some of your lines get broken. That way, you can create smaller areas in
  which you can catch the pesky little things easily.


WHY:

  There's a game for MS Windows called "Jezzball". You may notice that this
  one is extremely similar. There's a reason for that. See, our main
  computer at home runs Linux most of the time, but it has Win95 set up to
  dual-boot if need be. (Unfortunately, it's too slow to run VMware or Wine
  well.) Ideally, of course, the machine stays in Linux, but my wife, Karen,
  really likes puzzle sorts of games and became highly addicted to this
  Jezzball thing. Well, we simply couldn't have the system wasting its life
  in Windows all that time, so I took it upon myself to create a
  sort-of-clone. (It's not a pure clone, because I like to think that I've
  done many things in a far superior way.) So this game can be thought of,
  in a simultaneously dangerously geeky and dangerously mushy way, as sort
  of a dual love-letter, to both Karen and Linux. :)

  It's therefore somewhat ironic that IceBreaker now exists in a MS 
  Windows version. Ah well. I know not all of you have been converted yet,
  and you might as well enjoy the game too.


WHO:

  This game was written by Matthew Miller <[email protected]>.

  Recent versions have benefited immensely from the help of Enrico Tassi
  <[email protected]>. He's responsible for getting the Win32 port
  to work so nicely, and for a lot of fancy new features. Enrico doesn't
  live here in Boston, but he's a huge fan of Boston band Letters To Cleo,
  so that counts for something.

  Much thanks to Karen for everything. In fact, if you really love this
  game, check out Ten Thousand Villages <http://www.tenthousandvillages.org>,
  the non-profit organization for which she works. And if you live near
  Boston, MA, stop by the store downtown by the Freedom Trail and perhaps
  buy something -- they have cool stuff and it's a really great
  organization.

  Thanks also to Tae-Jin, for helping me squash a nasty bug, and to Paul for
  testing and suggestions and proofreading this document. And to the folks
  at the helpdesk downstairs for playing this game instead of working.

  The sounds were either originally created or borrowed from freely-licensed
  sources and modified heavily. Thanks to Wesley Crossman for his
  contributions. I'd still like lots more cool good ones -- either
  improvements of the existing sounds or for new themes.

  The penguin image is mostly my own work, but is based on a graphic
  from Pingus <http://dark.x.dtu.dk/~grumbel/pingus/>.

  Actually, I'm quite open to accepting any help anyone wants to give.


WHEN:

  A week or two in September 2000, and then some more time in July 2001,
  and then in May 2002, and so on.

  And now! Updated in August 2020 for a 2.0 release and inclusion
  in the Fedora distro. Because it's about time.


WHERE:

  Get it from: <http://www.mattdm.org/icebreaker/>
  
  Report bugs: <[email protected]>


WHICH:

  (As in, "On which libraries does icebreaker depend?")
  
  libSDL and libSDL_mixer. <http://www.libsdl.org/>

  Currently, it requirees the 1.2 version; porting to 2.x would be a good
  idea.


WHITHER:

  I'm not actively working on IceBreaker, but I'll take patches.
