From the box, in portuguese:
"È um castelo assustador, tem 2 andares, inúmeras dependencias horripilantes, onde vivem fantasmas, vampiros, mumias e lobisomens, todos tentando impedir que a princesa seja salva, Mas você pode salvá-la e ser o vencedor do jogo. Basta ter muita coragem"
"It´s a haunted castle, two floors and countless grim rooms where ghosts, vampires, mummies and werewoves lives. The monsters are trying to keep the princess captive, but you can save her and be the winner of the game. It´s only a courage matter."
The game is quite simple. Explore the castle and be aware of the monsters. Each monster have some weakness. Vampires are killed by wooden stake , werewolves by silver bullets, ghosts by the light of a lantern and mummies by knives.
