On itself, that's quite the challenge. It's practically impossible NOT to take Fall Damage after THZ1. But losing all of the rings in a fall is quite disappointing.
If someone has the same problem as me, I recommend the ringkeep.pk3 addon. It gives extra realism to the base game and combos into this one, making it a lot more bearable.
EDIT:
As I said in my review, losing all of the rings just because you fell too hard is not that good. One thing I suggest is the following: instead of damaging the player if they go down at more than 30 fracunit, you could make the player lose a certain percentage of their rings depending on the height of the fall, but never losing more than, idk, 50% of the rings. And, maybe, if the fall is not THAT big, just play the damage animation without actually damagin the player.
This would make playing with the mod a more immersive and realistic experience while still leaving it fun to play.
