Entry 6 -- Ender's Game

What is the climax of this novel? what happens? how do the events of this novel make you feel?

I think the climate of this novel is the part when Ender plays his last game, which was the real war against buggers. Ender just thought it was another game, but it was the real game. He had won against many buggers, and began to be loved by others. The event of this novel make me feel quite confused, because the the last game, that I thought was just like other games, suddenly turned out to be a real war.
