I had purchased Lugaru HD via one of the Humble Bundle deals, but have only just tried to play it. It comes as
.bin which can be run (after changing the permissions of the file to
allow executing file as program) in the terminal, to install the game.
Graphically the game runs smoothly, however there is no sound.
A google search comes up with several solutions suggesting to run the game each time via the terminal command:
padsp /home/username/lugaru/lugaru or pasuspender /home/username/lugaru/lugaru
Which plays sound... but horrifically crackly.
