My favorite games are the ones that embody some sense of freedom, and I just don't get that here (at least not from the first 3 levels). I completely understand Nintendo's decision to go with the single-finger jump-only game mechanic for a touchscreen device (I've never been a fan of virtual D-pads). But unfortunately, that decision has transformed Mario from a game about discovery and freedom into a game where you're - quite literally - not allowed to stop and take a second look at something.
As a natural consequence of this change in game mechanics, we seem to be forced into a constant state of hyper-focused speeding through what might otherwise be an attractive setting with subtleties to be explored. If I pass something that looks interesting in Super Mario Run, I'll likely never see it again (no, I'm not really motivated to repeat levels for coins - but I would be inclined to explore new paths through the game if I weren't always forced to be on the run).
Making matters worse, the few times I did attempt to explore a little (by jumping back off the walls), the clock ran out in what felt like an unreasonably short time compared to other Mario games.
In the back of my mind, it feels as though this change reflects something more profound about how society has evolved in the past decade. Maybe our competitive and demanding nature has overshadowed the desire for individual discovery and creativity. We don't need a landscape-oriented view of the horizon anymore; we only care about what's immediately at hand in our myopic view of the world because, let's face it, this is 2016 and we're too lazy to flip our phones around to landscape mode, let alone to confront the harrowing idea of plotting our own course through life. Just put us on the conveyor belt and tell us when to jump - and how high.
OK, that may be taking it a bit too far, but I'm still not buying the full game - and it has nothing to do with the price.
