you go to a game like the red circle and the go to the exit then it will say go to next
level i know i got stuck on that too

Do a couple of the tasks, then go to a game that you've already done and talk to the king,
there will prob. be an option that says "Go to next Level" select it. If that option
doesn't appear, then play a couple more games. It should appear after 3-4 games.

Notes: In my opinion, the chicken game,the rat game, and the troll game are easyest...
