I give you a perfect score, yet...
It can improve so much.
First, the rotation got confusing, because you're turning from the bottom, not the top. Maybe other people do better rotating from the bottom, so you might make that an option. It would be easier to get a lower score if you didn't accidentally turn it the wrong way.
Second, you need a greater selection of songs. That one song kinda got annoying. (not to mention the 'no volume sliders' thing)
Third, maybe have an option where there are different textures and color schemes, or even just a random texture for each puzzle.
Fourth, make more puzzles, or maybe random puzzles, or something.
It's really good. But there's so much more it can have!
