After the longish article 6 about melee fighting, we're going to take a break and do something easier.

• First, we're going to slightly improve the player health bar with some visual fluff.
• We will also move the game log from the standard output to the game window.
• Finally, we will start to use the mouse and implement a mouse look feature to display information about what is under the mouse cursor.

These are three very distinct features but for the sake of simplicity, we will stuff everything in a single Gui class (for Graphical User Interface).
