VerTris: A 2-Player HTML5 Tetris Game

VerTris is a modern, 2-player Tetris game built with HTML5, CSS, and JavaScript. It offers a local multiplayer experience on a single screen, complete with PS4 controller support and competitive mechanics.

Key Features

• Local Multiplayer: Two players can compete against each other on the same screen, each with their own game board.
• PS4 Controller Support: The game seamlessly integrates with PS4 controllers, providing an intuitive and console-like gaming experience.
• Keyboard Controls: For those who prefer a classic setup, the game also supports keyboard controls for both players.
• Garbage Line Mechanic: Clearing multiple lines sends "garbage" lines to the opponent's board, adding a strategic layer to the gameplay.
• Hold Piece: Players can "hold" a Tetrimino to save it for later use, allowing for more strategic piece placement.
• Ghost Piece: A "ghost" of the current piece is displayed at the bottom of the board, showing where it will land. This helps players plan their moves more accurately.
• AI Opponent: If Player 2 is idle for a certain period, a simple AI takes over, ensuring the game can still be played.
• Modern Aesthetics: The game features a clean, dark theme with neon green accents, providing a visually appealing experience.
