While Aang was on his journey to become the Avatar and find out all of his Profession skills, he was approached by Princess Azula. The ancient technology of shaft leaning was his only hope to win that battle.
In difference with previous version here you are going to have to fight against monsters. Your task would be to kill them all and find the exit door. You can't loose but being captured by any monster will bring you to the game's beginning. But sometimes it freezes (if no - click sperm button). If nothing happens - restart the game. Or better try not to loose in the battle. Use arrow keys after each assault to escape and then go back (when you refill energy at the water fountain).
