Please, I'm very new here, just found the place today, but Cave Johnson told me to post this link here when I showed it to him.
http://pixelships.com/adg/ep0096.html . ADG stands for Ancient Dos Games. never would have heard of this game without it. I sent ADG's creator an email today mentioning this place when I found it through wikipedia. Not sure if it is freeware or abandonware. Going to play the game soon for the first time however. sorry, I ramble.
