Tetris

A terminal-based Tetris game written in C, running natively on Windows via the Win32 console API with full ANSI color support.

✨ Features

• Classic Tetris gameplay — all 7 tetrominoes (I, O, T, S, Z, J, L)
• Hold piece — swap the current piece into reserve at any time
• 5-piece queue — see the next 5 upcoming pieces
• Ghost piece — shows where the current piece will land
• Line clears — single, double, triple, and Tetris (4-line)
• Progressive difficulty — speed increases every 10 lines
• Score system — points for soft drops, hard drops, and line clears
• Colorful ANSI rendering — each tetromino has its own color
• Main menu with keyboard navigation
• Leaderboard (coming soon)
