Cosmic Spacehead — About this game
Cosmic discovered Earth, but nobody on Linoleum believes his story. To return with proof, he must explore towns, talk to their inhabitants and find uses for the objects he collects. Adventure scenes use a cursor and a choice of verbs rather than direct movement. Travelling between places brings short action sections where Cosmic must jump over hazards. Progress comes from understanding the surroundings as well as handling those journeys, so inspect objects before trying combinations at random.
