game ideal

The game I'm thinking about is going to be European history based. You're in a castle and the only way to escape the castle is to answer the question that the monsters ask you. Once to make it to the end, the main villain appears. In order to get pass him you need to answer 5 question in a row without messing up once. If you mess up just once on any question, on either the monster or the boss, you will go back to the very beginning. Each time you answer a question correctly on the boss level, he will slowly revert into a nerd. Once completed, the game will end with the a girl waking up revealing it was all a dream.
