You know what? Even with some small problems and glitches, it's a really fun game. The level design is very intuitive, the cry to find collectables is really helpful and the worlds the team created are really cool to explore. The lenght is also really good, it took me 12 hours to complete it 100% (Having every colletable appear on the map after finishing the campaign was very helpful).
I would say that the combat is not very fun, but it's totally skippable and never frustrating, the only time I got annoyed was at the end of the pig spirit's level, but that was only one time.
