This week I recreate an old text game that I remember as a kid in the '80s: Hunt the Wumpus. It apparently started in 1971. Basically you wander around a map trying not to fall into a pit trap or get eaten by the wumpus. You win by shooting the wumpus - but don't shoot yourself!
I use a "struct" to create a datatype for each of the rooms in the map. Also; a giant switch...case block controls the whole thing. The video is a much shorter 3 and a half minutes.
