Gravjumps are Instant, there is literally no time to move on the ship. And the loading screen for gravjumps takes a second or two on my very middle class system, yes it short fades to black but why should I care?

Maybe I am way more tolerant to loading screens because I am old and my first experience were with C64 and Amiga 500. Or maybe I just like the game so much that the loading screens doesn’t bother me.
