Definitely a great Concept. Reverse ideology of Can & Mouse. Was very fun to play.
OK, Suggestions... First, there is a LOT of inertia. I phase through all objects I want to interact with, and can't take a desired position ever. Maybe it needs to be reduced to make the cat stop movement in a shorter time. Next, please move Interact to [F] butt on. And last, would be nice to have a minimum Jump velocity, so it will be possible to Jump for a minimum height if the space butt on wasn't held.
