This is the classic game of Tetris, brought to us by the masterful Alexey Pajitnov in 1985. This version is programmed in C# for .NET 2.0 using the System.Console class. Because of the aspect ratio of the console window, I had to rotate the play screen 90 degrees for a reasonable game.
I wrote this game on January 14th in under 3 hours. It was a personal challenge to see how quickly I could make the game. .NET 2.0 helped out quite a bit.
