Interacting in the game Left-click selects objects and NPCs in the game, while right-click activates an object 2moons gold or talks to an NPC. The mouse cursor is context-sensitive; if you move your mouse over an object that you can interact with, an icon will appear on your mouse cursor indicating the type of action that will occur if you right-click (sword = attack, cog = manipulate, speech balloon = talk, etc.)
