You need to maintain your gauge well starting from the drill section... if your health starts dropping there, it's game over. But if you keep your gauge up through the drill and enter the final section with full health, you can clear it by using a tiny bit of precise hits and mashing. I used this to enter the 24 level, but the mashing wasn't exactly easy.

Depending on whether you can do the side brackets, there will be a lot of individual difference. Even if you can't do the side, it's a good length for mashing, so I think it's correctly rated as low-tier.

If you try to twist a chart that requires mashing, you'll experience the sheer brutality of a 200.

I'm just a passing 8-player, and I've successfully infiltrated 24.
