Tetriz

## Description

_Tetriz_ (not to be confused with the other games by the same name) is a
_Tetris_ clone running either in a window on the Workbench or on its own
screen. It is level-based, so clearing a certain number of lines resets the
playfield and raises the difficulty. Higher levels are not only faster, but
introduce blocking bricks and super-fast bricks. It is a well-featured
implementation, with various bonuses for high drops, multiple lines,
completing lines of one single colour or clearing the entire playfield.
