Stuck at Master...

The Master is really a wall, isn't it? I struggled at first too. Can you tell me which part of which song you're stuck on? Let's find a way to beat it together.

I recommend starting with lower levels and gradually getting used to it, adjusting the speed and such! Going too slow can actually make it harder, so I personally 'repeat a few times to find the optimal speed → identify difficult sections (understand what kind of patterns are tricky) → practice on auto'!

Maybe it's to intentionally play at a level above your skill to get used to the speed?
