I sort of had the feeling that its impossible to achieve that score, but I turned to the easiest mode and I did achieve almost perfect score, so it was not really that impossible. I understand that timing the eyes to be on the beats would be much harder to time the monsters, but when players feel like they have done the best and the game is not rewarding accordingly even in normal mode, it probably needs to tune down a bit. Here I suggest a very quick fix is to not use the same scale of points for final ranking the same in all modes, like in normal mode the score scale could possibly be lowered a bit, which makes sense because there is a reward for catching up with faster speed.
