Maybe adding some sort of obstacles that you have to watch out for would be an additional way to add skill expression. I felt that the game was mostly about clicking as fast as possible, and if I remember correctly, there was a definitive time limit. So, generally some more depth here would have been nice.
The leaderboard system and game are very polished, and I can see how this would be great as a jam game, but maybe the cat is also moving too fast. Not for difficulty tuning as the game was very simple, but for a longer run.
