brickshooter is a small puzzle game where you'll have to clear the central area from different colored bricks.
You can control the game with either the mouse or the keyboard.
Cursor keys, 'Z' and 'X' change the selected brick, and space will throw that brick into the playing field.
This is a clone of a windows game with the same name, though there are some small differences.
brickshooter also accepts some commandline parameters:
--help or -h Shows the commandline options.
--level=N Start playing from level number N.
--levelset=NAME Load a set of levels from file NAME.
--debug=N Sets debugging output level to N.
--fullscreen Turn on fullscreen mode.
--random=N Play a randomly generated levelset of N levels.
--nosound Disable sound effects.
