Trade has been added to the game.
You can meet the merchant in the city of troglodytes. As money troglodytes use beads, several of these beads are near the merchant.
In the future I plan to add another merchant with a wider assortment and place more pickable beads in the game.

Also.
- Injured NPS now correctly loaded health when the game loads
- Fixed a few bugs with the weight of items in stacks.
