Someone has probably posted this before. As usual, I'm too busy (lazy) to look.

Here's an EASY tip for tower. Instead of running through the first floor. Kill those first 6 mobs. They are soooo easy. Then you can skip the 5 dogs and the giant pig on the next floor. IMO, this is the hardest group on the map. And in the right situation can be a nice death farm when they are gathered around the spawn point. Sometimes requiring a force close.
