Making Designers Happy

One of my goals whenever I am programming is to make adjustments as easy as possible for designers. My system for item management allows anyone in-engine to edit the cost of items, their description, item type, and activation conditions without touching any code. Here is what an item object looks like in Godot's inspector!

Item effects rely on a global Game Manager class, allowing them to access the state machine and override values such as the round results and player inventories. If I were to code this project from the start again,  I would like to add an extra level of variable protection here as this is not an ideal approach if other programmers were to join the project.
