The class that I am a teachers assistant in was making games, and i was pretty bored. So they had been working on it for the past quarter and they all sucked hard core, I went bitch please and sat down at my workstation and downloaded dat shit. So i spent about a day and i made a fun little 70s style 2d fps, like at the old acrade games like this one
