I think the always-online thing is a DRM thing. I could be wrong, though.

As for the game itself: I've played it, and it's a pretty decent runner with the physics of New Super Mario Bros. Wii/U, but it's just not the same as the more full-fledged games. It's fun to pick up and play, but not groundbreaking or particularly special.

I was really disappointed by that choice. I had wanted to buy it for a plane trip I had shortly after it came out, but being online only, they lost that sale.

It seemed like an anti-piracy move because the game didn’t naturally need to be online. But I never thought iPhone app piracy was much of a concern.

And it required making an account to play. Instant uninstall without trying from plenty of people.

The online-only aspect of it killed it for me. I lived in an area with spotty cell service when it came out, meaning a game that would otherwise be a great time killer was unplayable due to the DRM.
