Press space to attack, and use the arrow keys to move. For the wand, move you mouse pointer to what you want to attack. To unlock the castle section, (the brown one) beat the other sections. The books will explain about all the monsters in that section but the boss. At the end of the castle section, after the last level, there will be a cutscene. Have fun!
Thanks to @scratch__girl123 for the cutscene.
