Pretty good overall

The other reviews say timing is bad, but honestly they must not know how beat games work. This game is more than likely better with headphones to avoid this "timing fail" that people speak of. Without headphones it feels like you have to hit early, but what people dont realize is you are hitting ON the beat, which means your finger does have to move BEFORE the beat so it can hit the screen ON the beat. Take this from an osu player (PC beat game) it feels weird without headphones but even without them I got almost perfect.
