Probably nitpicky from my end since I studied this stuff, but I know that IRL speleothems are exclusively calcite/travertine structures that form out of groundwater seepage and precipitation in the subsurface. So andesite speleothems or granite speleothems etc. are not really a thing. Since it's common to find calcite in pretty much every rock type I was wondering if it's feasible to change the speleothem colour/texture and in-game descriptor to strictly limestone? I think it would make caves look pretty nice too. Adding a weighting factor to certain rock types so they generate more in limestones, marbles and sedimentary rocks and less in igneous rocks when the world is created would also be really cool to see.
Loving the game so far, bought it a few weeks ago!
