Tetris Game

This HTML file implements the classic game Tetris, including tetromino (4-cell pieces) and pentomino (5-cell pieces) figures. It utilizes JavaScript for game mechanics such as piece rotation, movement, clearing of rows, and tracking the score. The game can be played on a smartphone by using touch controls or on a computer by using the keyboard arrows. The game is contained within a single HTML file and enclosed in script tags.
