controls:
Space to start game.

Info: 
Tetris is a game first written in 1984. It is one of the best known games ever
made and is fairly easy to implement.
This clone makes use of the Qt graphics API to produce the GUI and for drawing. 
Unlike many Qt projects, this clone makes no direct use of qmake, instead using
the CMake system for maximum cross platform compatibility.
