I got it yesterday, it's bloody solid. Did tend to demolish my battery a bit, but that night just have been because time was dissolving before by very eyes. If you commute or have to burn time a lot (I spent a lot of time in hospital waiting rooms recently) then it's amazing m no microtransactions either
It is one of the best games I've played this year. Really easy to get into for short bits, I pirated it first, played for a few hours on PC, bought it, played it for a few dozen more, and happily bought it for my phone.
