Tetris doesn't have a story. The goal of the game is to stack blocks in as quickly as possible. For each row that has no opening it will be cleared and points will be awarded.

The intro for this game is the logo for tetris then a fade to the menu.

The menu will consist of the title for the game “Tetris” at the top. In the middle will be all of the high scores for the game and at the bottom will be the play button. The play button will be able to be activated by either the left mouse click or the enter key.

The controls for this game are simple and cannot be changed in game. The enter key on the menu will initiate the game. The left mouse click on the play button will also initiate the game. During game play the user will be able to use the arrow keys to move the pieces. The left and right arrow keys will move the piece left or right on the screen. The up and down arrow keys will rotate the piece either clockwise or counter clockwise. The space bar will pause and un-pause the game. The ESC key will return the game back to the menu.

The background music needs to be a short repeatable loop that doesn't get on one's nerves. The music will be slow at lower levels and sped up at higher levels. This change in speed should be handled programmatically.

The sound effects will be a crashing sound for the blocks locking into place. The removal of a line will be a cheaful sound, something along the line of bells.

The movement of a piece could have a “click” sound associated with it.

This is a strait on view of the board. The camera will not move. Reference the concept art Game Board

This will be a simple engine that is based on a timer and a game state. The execution loop will consist of:

get user input calc movement calc collision draw screen

They are simple games keep it that way.

Most of these elements will have their own design documents.
