Can you describe what you’re doing when you fall off? I and testers have found it to work pretty consistently, so I’m wondering if there’s either some issue that I’ve entirely missed, or if the mechanic has been explained poorly.
To make sure it’s clear, the intended use of the mechanic is to hold down the strafe key (ctrl or alt), but before that, make sure to face either towards the ledge’s wall or away from it while moving.
Corners (both inner and outer) don’t require strafing. However, you’ll need to change the direction Lathe faces to account for the next ledge.
I will say that intentionally jumping off a ledge is pretty unintuitive. That’s something I plan to change.
