What's really helped is that my partner has taken an interest in it even though she normally has little interest in games. To the extent that she has been looking up tips and online manuals to help me as I figure it out.
Although it's quite simplistic at heart, it's a very relaxing game to play,slowly raising and flattening the land and you know a game has gotten into your head when you start seeing things in real life and trying to interact with them by subliminally "clicking" on them...as I've found myself doing with uneven patches of the road into work today!
