The presentation is excellent, being a cat is awesome, but game is quite lacking in the gameplay and story department. The game overall fails to give you satisfying things to do, and the plot is very predictable, unoriginal, and boring. The concept is bold and interesting, I wish it did more than that in the execution. That all being said, this is a short game (finished it in about 5 hours), so, the gameplay mechanics given to you in the game sit for just the right amount of time for you to enjoy them. $30 is pushing it IMO but it's up to you.
