I played a few songs and enjoyed myself. Not every note is on the beat. I couldn't tell if its just because the target timing wasn't perfectly timed out on the BPM, or if it was intentional. Having intentionally off-beat notes can be okay when you have enough notes always visible to quickly catch when something is in-between beats or syncopated or something, but as few as there were on screen at a time, it was hard to visually know when I'm aiming for something on beat or off without playing staring at the box as opposed to clicking to the music.
