Looking for name of game.

A discussion at work today centered on some early computer games. One game I use to play involved moving a little guy through various mazes. Some mazes required gathering different keys or avoiding a monster or two. The game had many levels and you were given a password when you completed each maze. Does anyone remember the name of that game. Someone suggested Charlie’s Adventure but Google shows nothing. The computer I played it on was an at the time modern Windows 3.1 machine. Any help would be appreciated.

Sounds like Chip’s Challenge.

That’s it, thanks a bunch.
