In Kudzu, you find yourself in a strange place after an ill-fated parachute jump. There are two files here because I released two versions of this game--the original in 1997 and an extended version with a new ending in 1999. I wasn't entirely happy with the original ending, but I don't think that the new ending was an improvement. I'll leave the choice up to you.
Burger Joint is a fast food restaurant simulation.

Llama Masters involves a team of some sort that travels to different places to defeat large enemies and report back to their leader, just to be sent out again.
