Netrix
About
Netrix is a clone of Tetris, released as a Mac OS X Dashboard Widget, that I had originally done around 2007 as a way for me to learn multiplayer APIs that had just been added to Unity. Recently I got my hands on the Jai Programming Language and decided to redo that project as it wasn't that complicated, I already had the assets, and could focus purely on implementing it.
Currently it doesn't have multiplayer support nor leaderboards like the original, and not sure when / if that will happen given lack of time.
It is meant as a learning resource for those interested in Jai, and as such full source is provided, although you'll have to wait for Jai to be released in order to build it yourself (check README.txt for more information).
To run the game, launch bin/netrix.exe .
Hope you find it useful,
