Not bad for a first effort
Seeing the sequence after you click the cat at the end was great, and I get the feeling you'll make a solid sim-date game in the future if that's your aim. As for my suggestions: there were some minor stylistic things that gave it a choppy feel -- the font change when you're picking a response in particular, the fact that it switches between at some points having you click on the text itself in the bottom box to go to the next page and then at one point you have to click on an arrow button instead, and the box at the bottom of the screen jumps slightly when it transitions between showing a response and giving you options to pick from. I'd recommend tweaking the platform so it does a color change instead of a font change when you mouse over a response, and make it so you can go to the next page of text by clicking anywhere inside the big box instead of having to click either on the text or on a next button, or maybe just always using a next button but not having it make people click on the text.
