I loved the first two OliOlli games. Played hours and hours of them on Vita and then again on Switch. They're the perfect auto-runner and, in many ways, share a lot of commonality with the decent Sonic games.
OlliOlli World has sacrificed some of the smoothness and fluidity for a lovely cartoon style and a character creator (which I normally hate but is quite fun here). I have skipped 100% of the dialogue sequences - I'm not sure why developers do this. I just want to play the game. If the game doesn't need a story, please resist the urge to shoehorn one in!
I think I'm about half-way through so I probably still have quite a bit to unlock, but I'm really enjoying having a new OlliOlli game to play.
