There is a big boss to destroy at the end of each level and there are
various ships to destroy before you reach each boss.

Use your fighters as weapons!
Strategic suicide is a powerful tactic!
Self-destruct to preserve your ammunition!

ENVIRONMENT
The following environment variables are used by chromium.
CHROMIUM_SCORE
specifies the location of the user high-score file.
CHROMIUM_DATA
specifies the location of user-customised game data with the
same layout and filenames as the system one.
CHROMIUM_FONT
specifies the location of the font used in the menu and the
game.
FILES
The following files are used by chromium.
~/.chromium
contains various chromium user preferences.
~/.chromium-score
contains the chromium user high-scores.
~/.chromium-music
contains a list of music to play during the game.
~/.chromium-data/
directory containing user-customized game data with the same
layout and filenames as the system one.
Chromium will also look in a system directory for data.
CONFIGURATION
The configuration file is a plain text file. Each line contains a key,
a single-space separator and then a numeric value (integer or floating
point). The following keys are recognised by chromium.
use_playList
Enable/disable playlist support. This causes chromium to open
the ~/.chromium-music file and play the files listed there.
Disabled by default. Only works when using OpenAL.
use_cdrom
Enable/disable CDROM support. This causes chromium to attempt to
play any audio CD that might be available. This is disabled by
default because the constant spinning up of the CD can be annoy‐
ing and because CDs are less popular than MP3/OGG these days.
Only works when compiled with SDL support.
full_screen
Enable/disable full-screen mode. This causes chromium to fill
the screen instead of just using a window. Disabled by default.
Only works when using SDL support.
true_color
Enable/disable 24-bit color. When disabled it uses 16-bit color.
Disabled by default. Only works when using SDL support.
swap_stereo
Enable/disable swapping sound orientation. Disabled by default.
Only works when using OpenAL.
auto_speed
Use an alternate speed adjustment algorithm in certain situa‐
tions. Disabled by default. Only works when using SDL support.
show_fps
Print the frames per second at the top right when in a game.
Defaults to enabled.
