Once upon a time, there was a Holiday party where many people got very sick. A young doctor, you, wants to save his friends, now patients, by fighting the disease. You found the most effective way for that - shrink yourself, and exterminate viruses and germs from inside. Your mission: travel through your patient's body, destroying evil viruses and germs, and saving the good blood platelets. Hint: some doors are locked and require keys. You will see the keys after scoring enough points. Good luck, micro-Doctor! And, don't tickle your friend too much. :-)
