Hey,
heres my first mod so keep in mind if its not that good dont go hating just tell me how it could be better
This mod adds a new biome called the hell biome. The ground is made of netherrack and lava is scattered around the biome. Trees are made of netherrack and are 100 blocks high with lava for vines and leaves.

In my opinion its a pretty good mod but thats probably because its my first mod...
Anyway here it is :P

If you liked this mod, please check out my new youtube channel here
