This was a really fun logic game with a very well made tutorial. Card prompts were the perfect level of "hint" to direct you to the next card without being too obvious, so I "felt smart" figuring it out. I had a great time with this game and expect it will do well in the jam.
Art and music were also good, though it would spice up the background a bit if it had some texture, like a faint outline of candy pieces scattered across the screen. Sound effects for flipping the cards could add some nice realism, though I see you only had a couples days to make it, so maybe you had to cut minor polishes like these.
