Sweet Middleground 2 ~the birthday cake~

This game is the sequel of Sweet Middleground:
A birthday is near, and Vincent wants to make something. He pushes Antigone to make a birthday cake together. Unable to escape it, she decides to get back at him, with a complicated cake and complicated errands along with it. Like the first game, it's a simili-VN with puzzles; but this one has some semblance of character animations (see gifs), and less puzzle guidance.
Unlike the first game, this one is heavily comedy-oriented.
Estimated playtime : less than half an hour.
