He also had multiple people telling him exactly where to go to get certain items at certain times so he could get the "good" ending. He also had multiple instances of just happening to go to places and mysteriously finding optional upgrades like health flasks, attack power, and so on.

He also beat the final boss (having clearly read ahead to prepare) in a few tries and acted like he was the greatest gamer alive, despite the fact that he had died hundreds of times to earlier bosses.
