Human Extinction (PIU Edit.)

It doesn't seem that hard, but the late spike length does all the damage:(

Comparing it to Ultimate Prima, a representative 21 run chart, the difference is clear.

A more reasonable difficulty adjustment than Full Moon.

It's a chart that slightly reduces the twist proportion compared to a GOODTEK of the same level, but increases the length of the runs. While playing this, I still wonder why it was downgraded, but considering it's mostly just raw runs, I don't think it's completely underrated. Depending on your run processing ability, it could be underrated or not, but if you're strong at runs, I recommend it.

There are almost no charts in 21 that can rival this 200 BPM raw run. However, since there are no twists, I consider it appropriate for its level. A run practice chart on the level of s21.9.
