Came for cats found a lot of them. :)
Graphics: Nice art style, I really like your cats. However, your ingame cats look from the top down perspective a little bit weird especially if you turn your character.
Music and sound: I think they are well matched and the level music fits very good to your general atmosphere. It felt like I was playing some good old retro game. :) I also like how the level music progresses with the time and becomes hectic.
Enemies: As already said, the enemies felt a little bit slow in my opinion and gave me the feeling that they weren't scary at all, since you could easily dodge them. Maybe it would have been good to have multiple types of enemies. Some who move faster or some which chase you for a certain limited time regardless if they in the alert range or not. I liked the exclamation mark on the enemies, though. Remembered me of good old Metal Gear Solid. ^^
All in all a solid fun well polished game. Keep up the good work!
