A boss will drop all its items A girl will choose a name from a list (not finalized) Carrots will no longer spawn randomly Lets a message overflow to the next line Added a new method for dropping an item at any location (for Boss.java) Improves backpacks Improves symbols for existing items Added an interact-message to all containers, and removed it from IStatic Makes it possible to get any of the 1-10 items in a chest Makes an item dropped on the same tile as a static container enter the container Code improvements Game end screen
