why not?
sure - not on normal jumps ...
But I think they shouldn't be able to jump far away if there is a high gravity, or should jump far on low gravity planets.
maybe we can add a time window without damage and if they fly much longer than they should need for jumping then they get damage.
If they take 125% of time they get 25% damage
If they take above 200% of time they get 100% damage
Maybe we need to add 10% and use 135% and 210% instead the values above to take care about all cases.
