Gravity decreases as you go higher from the ground! and there should be a gravity switch on your ship!! you know what can happened
I was about to post the about same thing before searching. Moons should have less gravity! This should affect falling damage either by a reduction or elimination
I was about to write a similar post. After a few hours of play and tooled up with a little armor and a decent sword I went planet hopping. It quickly occurred to me that different planets really ought to have different gravity levels, maybe even random 'character traits' could also added like you see in Rogue Legacy. You could have alsorts of potential silliness happening!
Gravity is already implemented, but for the sake of ease and balance, it's currently disabled, giving all planets the same gravity, this can however change during the beta and release.
