Short excerpt below. Read at the original source.
Hollow Knight: Silksong‘s double jump ability can completely change your ability to move around the map and fight enemies, but it isn’t that easy to find or unlock. You’ll need to make some headway into Act 2 before you can go for this upgrade, and getting access to it also requires some other movement abilities.
