Overall presentation knocks it out of the park.
Personally I had trouble trying to process circle and square notes from each other (played between AR 2 and 3) in the heat the moment - I imagine I’d be able to process them faster if they were color-coded with the same shape instead of two different shapes. No problems differentiating star notes, however.
A calibration feature would be very appreciated, because I felt the notes came fairly early relative to the music, leading to lots of early +300 judgments unless I purposely delayed my hits.
Also echoing the easy to drain, very hard to fill nature of the lifebar.
