Yeah they really are different. I've just noticed that some of the people who dislike NightSky seem to state its dissimilarities with WaDF as faults. So I figured I would share my opinion. But in a way, it's not the "on-the-surface" dissimilarities that make NightSky more enjoyable to me... it's the fact that it has a completely different soul. I love platformers and puzzlers. I love Knytt, Knytt Stories, Saira, and FiNCK... but WaDF is just not my cup of tea... while NightSky most certainly is. I just found that interesting.
