[Suggestion] Cave Types / Variety

Since caves are a crucial part of the game having variety would be awesome to make the experiences a "Wow" factor. Not for all of them but like -

Having Bats or some alien life form live within.
Having Moss growing. Water dripping from the surfaces.
Bioluminescence plants or worms as well.

Giving more platforming to caves to get to certain nodes. I mean there is jumping already but incorporating using ladders more perhaps.

High risk high reward caves that are perhaps in locations that if you not ready to get to them you will die for sure but the resources inside are well worth the effort. A cave that is high up a cliff and therefore atmosphere gets thin (or a debuff) so oxygen consumption is much greater and winds affect you greatly. as an example and its quite the hike to get to it as well. is not just around the corner.

More underwater caves. some that are hidden sneakily and perhaps some whereby you have to crouch for a distance which then opens up into a much larger opening.
