Here I made some pretty huge changes. 

I restructured the project to make it possible to scale. I made it so that party stats, items, and equipment are all stored in json files. This made it possible to add a working 'save' function to the came so progress can now be continued. 

I added a large inventory of equipment, along with a function to randomly generate equipment. Equipment has a variety of possible add-ons attached to it, such as increased damage, resistance to bleeding, resistance to blindness, increased movement speed, first strike, etc. Enemies have a chance to drop a randomized piece of equipment, whose effectiveness scales with player level. 

I also added two in-game stores where you can buy items and sell anything you have found while exploring.
