Frustrating at times but also appreciatively rewarding. :) The mechanics are intuitive, the obstacles varied, the coordination challenging. Love the music. Groovy, soothing when the frustration lingers, it changes up refreshingly often too...
Suppose grueling sessions of Angry Birds earlier might've prepped me for this, apart from level 18 I didn't get stuck on any one level all too long.
Good fun!
