If you can jump from something high enough to allow you to reach terminal velocity, hitting should not really be felt for a couple reasons.
1: have you ever fallen off of the monkey bars at school (only applies if you're around 30 now, since playgrounds are banned), and hit the ground? Yeah, it doesn't really hurt if you hit hard enough and don't twist a joint or hyperextend something. You feel the pain later, though.
2: If you hit hard enough, your head will whip into the ground and pretty much paste your brain before you can feel any pain from the initial impact, which would likely stop your heart as well.
I'm only basing this on the non-fatal injuries I've experienced in the past, with my useless knowledge of basic kinematics.
If you can keep your eyes closed the whole time, you won't tense up right before impact or reflexively try to land the "jump", which tends to leave one with shattered limbs, ribs, pelvis, and spine, protecting the all-important brain at the expensive of everything else. So that's a long and torturous death.
