WALKTHROUGH:
Level 1: Click on hint, then click menu. WAIT! Dont click continue. After about 30 seconds, when it transports you to the menu, level 2 will be unlocked.
Level 2: Click on the doorknob of the castle. Then, click the leg of the spider on the ceiling. Say 'no' to the key. Return to the menu. NOW, right click on the level 3 box. An option play- should be aviable in the white box that pops up. Click that.
Level 3: DONT DO ANYTHING! Like level 1, wait until you are transported back to the menu. Use the right click technique to open the bonus level too.
Bonus Level: Er- pokemon? Nothing to do here as much as my eyes see...you can click on the sun to start over.
Thanks! This guide has been written by me, except somebody who said to right click to access level 3. Thanks!
