F.L.A.W. is available for various systems. It can be build on any platform supported by SDL. At the moment there are packages for Linux and Windows available. If you have built the game for any other system or include it in any Linux distribution, please let me know, so I can mention it here.
Download the latest zip archive and unpack it.
Before downloading any packages, please check if FLAW has been included in the official repositories of your linux distribution. It is always the safest and easiest option to install software from official sources through your package manager.
Others: Download and compile the Source Code.
