Nintendo's EShop Indie Failure?

I thought The Mysterious Cities of Gold would suck to be honest because a lot say it's bad and all but I thought I give it ago because looking at it from trailers looks great? I have played many hours in to it and I love the adventure/puzzle game feel to it. I wouldn't say it was a waste of afford of getting it and being judged by it looks than actually trying I think first is not good for any games.
