Hey! First of all, I liked your game, it reminds me of that golden era of Flash Games, which were very simple but could stiil entertain you for a while :D
But a little something that I just couldn't help but notice it's that the cat sprite it's very blurry, which could be caused by the settings of the import when adding the cat sprite. A possibility to make it not blurry it's setting the "Filter Mode" to "Point (no filter)" and the "Compression" to "None", it's usually used for Pixel Art, as far as I'm aware
(Also, "Cat-fish" it's a genius name for a game, I loved it :DD)
