Kosmonaut (1990) - Bluemoon Interactive This file is written by Retro Hideout. It is not a licence from Bluemoon Interactive. The archive kosmo.zip, offered by Bluemoon Interactive on its own page (http://www.bluemoon.ee/history/kosmonaut/index.html) "to see and try the game in whole", holds one file, KOSMO.EXE, and no licence text. The page states no distribution terms. Retro Hideout hosts KOSMO.EXE unmodified, free to play, with credit to Bluemoon Interactive, under its availability-and-owner-removal policy (see /rights/). It is taken down the same day if Bluemoon Interactive or any rightsholder asks: https://retrohideout.com/rights/contact/ For comparison, Bluemoon's freeware readme for SkyRoads (hosted on this site) allows free distribution of unmodified files as one unit. Nothing says that readme covers Kosmonaut.
