I want to add more puzzles to action games. Zach and Wiki was an awesome puzzle game, where monsters you fight turn into tools, and if you do the wrong thing you might randomly die. It would have been a lot cooler if you could control your movement with arrows/joystick instead of point-click. Point-click games get pretty boring. Games that challenge the mind, more than just knowing weapons and how to use them, is an idea that is more fun to me. Designing puzzles is a lot of work though.
