I love the idea, but as i understand there is only one actual scene in the game. And you can get same endings with different cakes, which I didn't find particularly intuitive.
I liked the little game, but if you would ever expand i'd recommend adding endings to every (similar) combination of cakes and giving every single one at least an image or something special about it if that isn't possible (like a red background and blood, or pink flowers, or lightning, etc.). One image and a simple story is enough for a scene. Just so we know what is going on. Doesn't even have to be nsfw.
