p1nkpong / monopong

p1nkpong / monopong was my attempt to write a full Windows OpenGL within 1KB (ie. 1024bytes) only. monopong was my first attempt. After a lot of optimization (thanks to auld) - I created a new version (named p1nkpong).

The gameplay lacks a bit since it was more a proof-of-concept that it is possible to create such a small windows game.

Screenshots

Features

- Windows game in 1016 bytes only
- OpenGL graphics
- sound system (midi)
- (binary) scoring system

Usage (p1nkpong)

The game starts immediately. Press ESC to quit the game. Use UP/DOWN cursor to control. The scoring system is shown in the middle screen. It represents teh score in binary form.

The control in monoPong is slightly different. Please refer to readme.txt file in archive.
