Worked my way through all the 40s and now I’m onto the 50s. Some of the levels seem to be really, really hard, and then you get a stupidly easy one. Is this right? Or am I just not doing them the way you’re supposed to? Most of the levels I’ve tried so many times that you get the “start here” hint on, I haven’t started where it is suggested and done it another way instead. Well, it doesn’t matter in the end, I suppose.
