Since no one has said it yet ... after level 3 do not get the magic upgrade until level 7. If you do it that way it's a little more work but it will save you from having to start at the beginning again. Also, for new players, the boss level is not the hardest room in a level. The hardest room in a level will be the second room you go into, because you will not be able to heal before it and (if you don't get the magic spell, as I suggested) you will still have the damage incurred from the previous boss room. Prepare for this.

So THIS is what a girl's life is like! Find the guy of your dreams, extra points if he's the skin color you like!

But it's okay because happiness is the real goal...except if you're over 50 then nothing matters anymore.
