This is a really beautiful game; the animations and sound effects compliment each other. My suggestion would be making the transitions and the showing of results slightly faster, since the actual gameplay is only a few seconds. Also, I would loved to see more of the flower pedal effects over the triangle effects, just personal preference. Finally, I wish there was a way to know how many total Ranks are there, or set a goal for the player. For example, prompt them with:"can you reach xxx rank?"
