A terminal-based Tetris game written in C++17, powered by FTXUI.

• All 7 standard pieces (I, O, T, S, Z, J, L) with 4 rotations each
• Wall-kick rotation system
• Ghost piece (hard-drop preview)
• Score, level, and line counter — level speeds up as you clear more lines
• Pause / resume
• Unicode block-drawing graphics

Level increases every 10 lines cleared. Drop speed increases from 800ms down to a minimum of 50ms.

FTXUI is fetched automatically via CMake FetchContent — no manual dependency installation needed.

macOS / Linux

# 1. Configure (generate build system)
cmake -B build -DCMAKE_BUILD_TYPE=Release

# 2. Compile
cmake --build build

# 3. Run
./build/tetris

Windows (Developer Command Prompt / PowerShell)

# 1. Configure
cmake -B build

# 2. Compile
cmake --build build --config Release

# 3. Run
.\build\Release\tetris.exe

Note: On Windows, MSVC places the executable in a Release (or Debug) subdirectory by default. Use --config Release with cmake --build and run from the matching folder.

# Debug build with Address Sanitizer (GCC/Clang)
cmake -B build -DCMAKE_BUILD_TYPE=Debug -DENABLE_ASAN=ON
cmake --build build
