🧱 How to Play Tetris

• ← → Arrow Keys to move, ↑ or Z to rotate, ↓ to soft drop, Space to hard drop
• C to hold the current piece and swap with your held piece
• Clear lines to score — clearing 4 at once (Tetris!) earns the most points
• Speed increases every 10 lines — can you survive the higher levels?
• Game ends when blocks reach the top of the board
