Easy experience:
Continue after defeating the first evil king (the rat). After defeating second evil 
king (the fish-like creature), return to the place where the first evil king was 
located, in the sewer. Once you get there, you will see bars that resemble those in 
a jail cell. Approach them and wait. A ghost will come after you. Let it get you for 
very good experience. The save and healer will also be nearby.

Easy Sukel:
In Tenel, go to the blacksmith's shop and talk to him. He will give you a Fruit Knife. 
Go to Madril and enter the shop. Talk to the kid at the counter. He will offer you 
300 Sukel for the knife. Do not accept his offer, and tell him that you will think 
about it. Start a new conversation with him and he will offer you 400 Sukel, which 
you can accept.

When you get a new sword, sell your other weaker swords.

When you get though the Aquatic Ruins, you can keep returning to fight the earns 
to get more Sukel and experience.

Sword Of Gear:
Tiny gears are scattered all over the world on the ground. You cannot see them, 
but if you go near them you will automatically pick them up. If you get 30 of the 
32 tiny gears and return to the house on the snow plain with a big snowman in 
front of it, the man inside will give you the "Sword of Gear". It has Attack +50 and 
Defense +10. If you keep talking to that man after you get the sword, he will tell 
you about the Turtle and the Pebble.

Finding the princess:
After the princess runs away, you can find her at your house in Tenel.
