This was so much fun! I can tell a lot of time went into tuning the cat's movement (which feels great!), and the little squash and stretch and rotate on its sprite are all really well done. I also like just how quick the restart is when you die. My only critique is that the slingshot move can get you through most levels without a whole lot of thought, so maybe consider limiting how often it can be used, or build some more levels where the right move is _not_ to slingshot, or something?
I also got such a kick out of the little transitions between levels where the cat just slowly slides off-screen. Hilarious!
Fantastic job.
