What is tetris-game?

This repository contains a working Tetris game built in C++ using OpenGL. It lets you play the classic block-stacking puzzle where falling shapes descend from the top of the screen and you rotate or move them to complete horizontal lines before the stack reaches the top. Under the hood, the game uses OpenGL to handle the graphics rendering. The README doesn't go into detail beyond noting the language and graphics library, so there's no further explanation of the game's architecture, scoring system, or additional features. This project would appeal to a few different groups. Beginners learning C++ could study the code to see how a relatively simple game comes together using a graphics library. Someone looking for a starter project to modify might use this as a base and add their own features. It could also simply be a portfolio piece demonstrating that the author can build a functional game from scratch. The tradeoff here is straightforward: because it's built with C++ and OpenGL rather than a higher-level game engine, the code is more hands-on and closer to the metal. That means it's a good learning example for understanding graphics programming, but it likely doesn't include the convenience features, polished UI, or cross-platform packaging that a full game engine would provide out of the box. The README doesn't mention build instructions, so getting it running may require some familiarity with compiling C++ projects and linking OpenGL on your system.
