Health is shown in a bar on the upper right corner. Your health will decrease when you receive damage from combat. If your Health reaches 0, you will faint. At this point you'll be given the option to recover and keep going where you left off by purchasing more Health. If not, you will pass out and wake up in the Clinic. When this happens, you may be charged by Dr. Phillip for medical care. You may also lose some of your coins and weapons. You will also 'forget' some of the levels in the mine and you'll need to retrace your steps.
