I'm glad that tactile feeling made you want to click more! I tried my best to do that with my very limited understanding of game feel without absolutely making the UI or readability a mess:) And yes, adding that bit of anxious energy was definitely part of the intent. I'm also happy that you thought the visual and sfx response was good, but it'd definitely be better if I could hand paint beautiful tiny cats like in your game!
(Oh, and if you like CLICKING there's actually a SECRET LEADERBOARD in the game that if you find it, it'll upload your HIGHEST amount of clicks...for no real reason other than it's another one of "the small things")
