What everything does: Look tells you what's on your screen Use allows you to perform an action, if you have an item equipped or not. You can tell if you have an item equipped if its outline is white. The arrows can tell you where to move, if they are greyed out you can't move. Maps have not been added yet.
The idea is this is like a point and click game. NOTE: this is a prototype, the UI looks bad because of that.
