I played through the first couple of levels and was instantly hit by how much better the level design, gameplay and characters were than the usual mobile game. I happily plonked down my ten bucks. I cleared the game in a single lunch hour, but I'm not disappointed. The game design easily surpasses anything I've ever played on my phone, and there's a bucket of replayability. Pink/purple/black coins to get, speed runs…
EDIT - I didn't realize that the first 3 levels were only what's available. I didn't make it past the 3rd level.
-- this game has dozens of context switches in the first 10 minutes, not even counting the uninteractable tutorial (Even other endless runner games let you run and figure out how to jump by tapping without 4 text boxes).
I will agree that the levels are better designed than the average mobile game.
Maybe my tastes are just changing? I feel that Nintendo has historically innovated in gameplay with their Mario games but I just wasn't sucked in this time.
EDIT
context switches in the beginning about "connecting a Nintendo account" and later, for push notifications - "Push Notifications are important" > User presses OK > Allow Super Mario Run to send you Push Notifications?
What is a Nintendo account & why would I care? What on earth would a push notification for a Mario game tell me? It doesn't feel polished to me.
