Hello Benjamin,
Welcome to the jam.
Best place to start I think is to load up the sample code and see how it works, also play TWO and check out the code for TWO.
The default theme (two) can be left in place, and you can tinker with it later on.
Try to keep your word count low, and build mood with items in your per location object list. There are two word limits per object, and two word limit per location description, but you can fill a room with as many items of scenery or objects as you want, and manipulate the object list as much as you like in response to player inputs.
I'm rambling. Good luck to you.
Chris
