This game hasn't got any great reviews but it was really fun to co-play. I played it with my wife and it was just the right complexity and difficulty. I could really recommend it.
As for playing it solo, I would probably get bored before I finish the first track. Didn't try out the level editor, even though Media Molecule is famous for those.
Game is not worth full price, but half price when you got someone you intend to play it with.
