I always find it fun when I'm given the option to kiss an annoying stranger in a game, and then follow up with a well deserved punch in the face. Love your use of facial expressions, and I'd like to request more belly rubs for Katie in the future.
I have been seriously considering how I can put in a kiss option for every single NPC... which should definitely include Katie, come to think of it. If I don't allow you to smooch that kitty by the next update, please get on my case. ;)
I will definitely get on your case if Katie being smoochable is on the line here. The world needs its balance between superheros, villains and smoochable kittens.
