Not much to it.
Scroll speed is way too fast for both songs, and notes don't appear to follow the beat or any other recognizable pattern.
Controls either can't respond fast enough, or the charting is too densely packed with notes to the point that it's not possible to keep up.
Medals don't unlock, either.
The cup is cute, and the look of the interface for the notes and health look good (and health certainly seems to be working just fine), but the gameplay is not there yet.
