Are you a classic computer game fan who would love to play a Super Mario style platformer on your Windows, Linux, and/or Mac systems? Then you may want to have a look at Secret Maryo Chronicles, an open source game ready to feed your Super Mario addiction.
The game comes in an installable & zip format for Windows, can be set up on a variety of Linux systems (i.e. Ubuntu, Arch, etc.), and will work on OS X 10.5 or later. Keep in mind that in most instances the background music will need to be downloaded separately and added into the program folder.
