Unfortunately, Rob didn't stipulate what "fancy" means. For instance: A* is definitely fancy, but it's neither buggy nor particularly hard to implement. And because of what it solves, there isn't even a simple alternative to it. I'd probably replace "fancy algorithms" with "self-invented algorithm" instead: you're not solving a new problem, resist the urge to "tackle it yourself" and just look up the almost-certainly-decades-old, and documented-by-thousands-of-people algorithm that's going to get the job done. (Of course, that'll be less fun for you, but if the only person who appreciates a piece of code you wrote is you, that's one of the signs that you wrote bad code.)
