I think repetition is definitely part of the problem. A vague hint is fine the first time, but it should get more specific if you keep struggling. Also, some of the hints only apply to the first move (or first two). If you find that move but get stuck later on, it's irritating to be shown an irrelevant hint. In this case I got the windmill started but for some reason the last move was in a blind spot for me -- though when I went back an hour or two later it was completely obvious (but that doesn't make it less frustrating when I was stuck).
