Week 4 Update

This week, we used blueprints to create doors and keys that increment a counter to a max of 11, as well as a green key and green door so they are useful for only themselves. The green key is a boolean that once picked up, allows the user to open any green door. Once a regular key is used at a regular door, the counter decreases by one. The doors are also coded so that they don't open and even alert the player they need the key in order to open the door.
