I am a puzzlemaker by trade. All my life I've been interested in games and puzzles, and how to make ones that are fun to solve.
I specialize in making puzzles that are simple but infuriating. I've gotten lots of comments from other people that my puzzles are evil and that I'm an evil person for making them, because once the answer is explained, it becomes obvious.
If the above sounds appealing, I have a puzzle/riddle book on my website just for people like you: http://joezeng.com/quetzalcoatl/
