Find the name of an old windows or dos game?

Hi, I'm trying to find out the name of an old game (windows or dos?!). There are no instructions to play. You start the game on what seems to be an alien world and have to make your way over pitfalls and timed traps. You keep dying as you figure out each stage untill finally you can make your way error free from start to finish. There are ape-like creatures that inhabit this world and consider you a combatant. They sometimes imprison you. I thought the name was "Lost" or "Lost World" but must be mistaken.. We used to play it back in 1993-1994 Can anyone help?
