re: the tutorial playing again when I hit rank 8 (i can't figure out how to reply to a comment), my progress and everything was kept, it was just the tutorial that popped up again!
Adorable, and very addictive, but I've found two minor problems. when I first got My Krooba out of the basket, it said he was a common cat. I think the same happened with Creme, although I can't really remember. and once I got to level 8, the game tutorial popped up again, introducing how to play the game and all that.

Oh no! So when you logged back in, the tutorial started playing? But did it keep all your progress?
