Firstly, good visual style.
Then, interacting with the cat using both keyboard and mouse is really fun. Kudos on the controller implementation!
As have been mentioned in the description, there are some area that soft-locked me from progressing further. One between the shelf, and another one I got stuck on the floor (cannot jump) on the where there is a moving platform.
Personally, I think the intro text is a bit slow. But maybe this was deliberate.
For lighting, I wish the immediate area around the cat is a little brighter to illuminate the cat's line of sight.
Overall, it's a nice little platforming game. Good job!
