A spacegame I do in my free time.
Linux only for now.
Allegro 5 is required for compiling and running.
Once allegro is installed simply compile and run with:
$ make
$ ./spacegame
You can compile with no dependencies using Docker:
$ docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp dimastopel/allegro5 make
