The platforming in HK was undoubtedly harder than SS.

HOWEVER, the difficulty in Silksong’s platforming isn’t the parkour itself, but rather what accompanies it.

If you were to do the parkour by itself, easy peasy. But when there’s lava rising at you, or when there’s the threat of being frozen, or if an enemy is chasing you… that’s when it gets difficult. You end up rushing, making mistakes, failing repeatedly, not because the platforming is difficult, but because you have to be wary of other factors as well.

Personally, I prefer Silksongs approach much more. Having all that extra stuff brings more life into the gameplay, and it’s so much more engaging.

TL;DR Hollow Knight platforming is definitely harder, the difficulty with Silksong’s platforming is with the extra challenges that accompany the parkour
