spaceship

Simple 2d spaceshooter game, built from the ground up with only C++, modern OpenGL and a few libs.

This is a build setup for linux.

Intended to be written as a single source file (main.cpp), with the most simple yet readable code that's needed to make a cool game.

Feel free to learn with the code, I am learning coding it too ;)

Status:
