This is my list of AGDG jam submissions.
The name of the game's engine is Jam-Operating-System, because it mimics a simplistic text-based OS internally (there is a command shell and various command line programs, running inside a RAM-backed virtual file system).
Works like MacOS, using allegro5. It became broken so it got fixed in generation 2.
Works like MS-DOS, using allegro4. So much easier.
