solid and fair review. I have this as well and enjoy playing it once in a while, but as you have said it is a relatively simple game and so nothing crazy exciting. Knowing when to play what cards does add some depth though.
My girlfriend loves to play it, though I think that's mainly because she loves cats. The simplicity makes it a good game to play casually, there's an NSFW version of the game as well which is just a different flavor text to the cards.
