Fly your Cosmic Cat to their comfy green cat to complete each level.  There are a total 210 levels filled with a wide variety of challenges.  These are split up into a main campaign (120 levels), a Training Mode (12 levels), a bonus campaign called Cosmic Kitten (60 levels), and 6 additional seasonal themed levels plus cats to unlock that will appear each season (totalling 18 levels until the Summer update, and then it will be 24 levels).

138 Unique Collectable Cards:  For you level explorers out there, each main level has a collectable card based on a something in the game. They will be easy to find in the beginning but will become harder to find later in secret areas.

(Training Mode levels will award you a Gold Star and an Arcade Coin for completing it, regardless of how long you take.)
