Great platformer.
You'll spend a lot of time getting all the gems and it didn't seem like you're following a path as much.
The Music was wonderful as always with catchy vocal tunes. Sometimes you'll just want to stop moving and listen to the music.
It gave it's surreal sense of humor again and was even funny during gameplay.
The bosses were very challenging and took a while for me to beat.
It also has a few cutscenes that bring back older villains from past games.
Once I collected everything in the game it was a disappointment and I put down the game and did not start a new for a while.
The cutscenes had better animation than in any other game.
Yet sadly you never got to see the birds outside of cutscene.
