Unnkulia One-Half: The Salesman Triumphant

You play by typing commands that describe what you want to do. In the game, you will find many objects that you can carry or otherwise manipulate. When you want to do something with an object, type a simple command that tells the game what you want to do; be explicit. The game assigns you a score while you play, indicating how close you are to finishing it. At certain points in the game, you will be awarded points when you solve some puzzle or obtain some item. The score is intended to provide you with a measure of your progress in the game, and increases as you get further in the game; you never lose points once they are earned.
Unnkulia One-Half: The Salesman Triumphant is not a typical DOS game in the graphical sense. It is a text-based adventure game, also known as interactive fiction (IF). It was released in 1993 as freeware by D. A. Leary and published by Adventions.
You play as Jay-Bob Tuckbucker, a down-on-his-luck Acme salesman working out of the Golden Dragon Inn, near the dangerous Dread Unnkulia. Your goal is to accumulate enough loot in this backwater area to improve your fortunes and potentially buy the local Inn (thus creating the conditions seen in the first "Unnkulia" game).
