• The game has several easter eggs, including a cameo appearance of the Batmobile outside of the evil witch's cave.
• In the "Pegasus" section, if you look in a hole in one of the screens, it'll play a quick demo for Space Quest, whose designers also worked on this game.
• Kolyma is, in fact, a river far in north-eastern Siberia, infamous for Soviet prison camps in this area. Millions of "enemies of the Soviet Union" perished in the whole "Gulag Archipelago", including the Kolyma camps, which were among the most terrible ones due to very harsh climate.
