Etude Op 10-4

The high note count makes scoring easy. Clearing it is on the harder side even among D18.

A chart where the difficulty is concentrated in the extreme late spike, so it can be good friends with BB D18. It's definitely tougher than Bang Bang D18.

Also, it's easy to find a way to handle the 6-half from the beginning to the end, and then handle the short run at the end.

Buffed from the previous D17. The first half is D17 level, but the second half is D19 level, so it seems they adjusted it to the middle. Since the late spike is short, the clear difficulty should be on the lower end among D18s.
