icebreaker - Man Page

An addictive action-puzzle game for X.




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 by melting lines without hitting any of the birds. Once 80% or more of the 'berg is gone, you advance to the next level.

Use the left mouse button to start lines, and the right (and/or middle) button to toggle between horizontal and vertical. Beyond that, it's probably easier for you go figure out the game by playing than by reading. So go.



-n,  --nosound

do not attempt to initialize sound system. Causes the in-game Sound option to be marked N/A, and the config file setting to be ignored.

-f,  --fullscreen

start in fullscreen mode if possible. Ignores config file setting.

-w,  --windowed

start in windowed mode. Resets config file so that this is the default. You probably won't ever need to use this, but it's there in case fullscreen somehow is broken and you're too lazy to edit the config file manually.

-tthemename, --theme=themename

select theme themename -- overrides config file. For more information on themes, see README.themes or the IceBreaker web site.

-l,  --listthemes

show available themes.

-v,  --version

display version and copyright information

-h,  --help

display simple command-line option help screen
