Afraid I ran into some bugs too; Completed vampire kid & fishman, but was unable to give the q-tip to the ear-man in starbucks, and the blood bank disappeared from the map after vampire kid (I grabbed the A+ blood... maybe it was supposed to).
Overall, pretty good game, I can only imagine how challenging an open-environment game like this must be. Wentworth was far better, however - not surprising since you made it afterwards.
