This is my Grade 12 Computer Science project that I created in 2015, named after the original PONG game released by Atari in 1972. It is built using C++ and uses the BGI library from Borland Inc. The executable can run natively on DOS only. It is running on this website using js-dos (kudos to @caiiiycuk for their awesome project).
*PS you need a keyboard to play this game, works best on PC but you can try the virtual keyboard on mobile. Press W to move up and S to move down.
Note: In the version running above I commented out all code that accesses the local filesystem to read or save files, a few functions have been disabled and the main menu no longer lists those options. This is ready to play version that does not require signup and does not keep track of the high score.
The source code is available on GitHub, and down below.
