I think it's cool that we both did dice based rhythm games! however, I had a pretty difficult time reading the "beat" of the dice. for one, I struggle to look at both the dice and my player character, since they're on opposite sides of the screen. and as far as matching a beat goes, I would rather have audio queues as the primary source of information, with visuals as secondary. and for the visuals, I would expect them to be moving at, or centered around, my character, in sync with the beat. there didn't seem to be a clear feedback for missing a beat / losing a health point besides the tiny label at the bottom going down, so I struggled to get a sense of when I was doing it right or wrong.
hope this feedback helps!
