vitetris is a terminal-based Tetris clone by Victor Nilsson. Gameplay is much like the early Tetris games by Nintendo. Features include:
Two-player mode with garbage
Joystick (gamepad) support on Linux or with Allegro
It has been tested on Linux, NetBSD and a few other Unix-like systems, and ported to Windows and DOS. Library dependencies are minimal (only libc is required), and many features can be disabled at compile-time.
Version 0.50 can run in graphics mode using the Allegro library, but blocks are still "drawn" as characters with an 8x16 console font.
