Nintendo Jumping

Just started playing this game and the jumping is utterly bizarre to me. Why on Earth (or Mars) does it feel like Nintendo?

There's something about the way the jumping seems too quick. Up and down in half a second, like you're smashing into a ceiling before falling down hard. Actually it doesn't feel like you're falling down, but that you're even "jumping" down. This would feel pretty weird to me even in most Earth-set games.

And when considering this is Mars, even with the realistically limited mobility of an EVA suit, I would expect higher jumps and slower falls. I would also expect jumping while running to give quite a range to each jump, and that it would take a little longer to both start and stop running. Nothing too exaggerated, but enough to actually make it feel like you're on a different planet. The physics of movement in this game feels even more constricted than games set on Earth at the moment, making immersion that much harder. 

Hopefully I'll get used to it. I really want to enjoy this game.
