This is my first released mod.
Note!: I'm bad at texturing, mainly the grilled coral because the rest is just the actual block.
Both Suggestions and Critiques are needed, but make sure to read everything first.
On to the main bit:
This mod adds a coral "stoneset" that lets you build with coral out of water, and with stairs, slabs, fences, gates, walls, trapdoors, and doors!
I mainly just loved the coral and wanted to use it as building blocks, and it's also annoying to supply water.
Upcoming Updates:
Possibly tools, though there will be a certain type of coral
Aquarium, supply the coral you want and a fish. Overtime it will produce more coral, such as, a tube coral block will give you tube coral fans, which can be crafted into blocks.
If I ever figure out signs they will come, they are an item via command but can only save text, they have no model or anything.
Most new versions will be updated, backports will only come if enough people want them.
