What to do on the first level
Start by choosing ESC,New Game, and Hurt me plenty. This will place you into the first room of the first level.

At this skill level, there are no monsters in this room, so you'll have time to orient yourself. Use the arrow keys to walk around. Explore the room. Pick up all the blue bottles (which increase your health), and helmets (which increase your armor).
