It would have been helpful to show how the keys actually affected gravity, but otherwise solid idea. 

Game was a bit of an odd one to get working, since the exe and pck were separate files. The "Back" button in the credits also didn't work. The perspective made it a bit hard to position the "cat," and speaking of which the graphics were a whole herd of ugly. I swear every Godot game I've played so far has been janky.
