While clearly a lot of effort was put into the game, and the animations are great, I feel the controls are a bit janky and difficult to grasp. When I think of a cat, I think of a precise jumper that can turn on a dime, or at least recover easily enough.
I think there are quantifiable steps that can be done to improve this however: one might be making climbable and unclimbable surfaces more apparent, and the ability to regrab climbable surfaces. Another might be to have a less zoom-y camera.
Overall, there is a lot of content and craft poured into this, and it could be polished into something memorable.
