tetris-cpp

A simple Tetris game implemented in C++ for the Windows console.

Features

Uses many global variables, making code harder to maintain.
Works only on Windows (conio.h, windows.h, Sleep, Beep).
Uses system("cls") which is not safe or portable.
Shadow block is not clearly visible (same character as empty space).
Random number generator is reseeded (srand) multiple times instead of once.
Functions canGoDown, canGoLeft, canGoRight have duplicated logic.
Rotation logic is simplistic and may fail for some tetromino shapes.
Whole code is in one file (no modularization with classes).

Refactor code to use classes (Board, Piece, Game) instead of global variables.
Make the game cross-platform (Linux, macOS).
Replace system("cls") with proper screen handling.
Improve rotation system (e.g., SRS like in modern Tetris).
Add unit tests for core functions.
Add music or better sound handling.
Add high score system and save progress.
