BOOOM!!

fun chart and the first half is chill. but the final section is like a D18 and confusing crosspattern, be careful

The holds in the first half are high-angle, you're right. Watch out for the half-notes mixed with holds in the late section after the 'ttagadan ttagadan' part.

I failed more on the early holds than on the late spike.

Just mash the final 4-half spike. For the early section, be careful as it requires more body movement than you'd think.

It's too difficult for a decent half-beat player or a 16-beat local to hit the late spike with full accuracy.
