TetriCOM is a game based on TetriNET.
But instead of playing with other people at net you play against computer.
Added a converted theme from TetriNET 2 at the download!. So it's not necessary to have or download TetriNET (or a theme).
The program requires to run Direct x and now it runs autonomous.
So when you download it, you unzip at the TetriNET directory (if you have it) write your nickname and start!
