Just beat the game on normal, I  liked it, I give it a 7/10. 
 
Best things about the game are the  visuals, characters, animation and facial expressions.
and the Cloud hover board!!
 
BUT there were a few things that I found  very frustrating ...

During the end of the game it was getting  very repetitive and tedious, I just wanted it to end, but you have to do one  frustrating  thing after another.
When you think you've killed the boss, think again, you have to fight it some more and then another 5 times more!!  they really drag everything out too much. 
 
The  camera was a pain at times.
 
Some annoying  puzzles, most of them were a nuisance and not very fun. It forced me to look online to figure it out, as it's not clear what you have to do in the game.
 
The Platforming gets  quite dull after awhile, as there is only one path to take most of the time. Often I found myself confused about where I had to climb,  running around looking for the 1 little spot that I was able to climb.  
 
Overall it's a good game with some very awesome moments and great characters but be  prepared to be  frustrated.

I beat it a week ago and think I would give it an 4 out of 5.
