Thank you very much for this nice message! :)
Currently the game is only available on Windows (full version and demo) because it was realized on the AGS wetness which proposes a compilation under Linux which is in phase of test and which is not yet confirmed operational. But if you have Linux and you would like to test if this game works correctly on your version, the beta demo for Linux is already available: http://adipson.free.fr/3geeks/3GEEKS-Linux.zip
If you download it and the demo works correctly (correct graphics and above all its operational sound, I invite you to report it to me by giving me your impressions at the same time on the game itself)
thank you beforehand !
