The Keaton in the game gives you riddles, so I'd have to stick with writing... or maybe luck because you have a 1 in 3 chance to get the question right if you don't know the answer. You know what, luck would give it the more mystical aspect that it has in the game, so I'd have to go with luck.
I didn't know you already had the first chapter out. It was good. Great detail, wasn't rushed, good emotions, all around good job. I also liked how in some stories the main character is too stupid to figure out they were different until they saw themselves in the mirror, but your character got it right away, and respond appropriately. Once again, good job.
