Some of those monsters in Midworld stomp you down early on. I think I died 3 times before I was able to make it up a level. Its really hard to earn money when you keep dying and don't have enough gold(because of the dying) to heal.
Fun game though. Anyone ever play "The Uninvited". I got to a point in that game that I spent hours trying to move forward without anything even trying to kill me. Hitchhiker reminds of that game. One of these days I'll figure out how to actually walk through the door. That day, is not today.
