New Adventure World is up!
Unfortunately, my original idea for this world will have to wait until I can figure out how to spawn Ghasts in a normal world, so I've provided something a bit different for now :V
In this new world, the only biomes are desert, jungle, and extreme hills. Ravines are now extremely common and caves are far more dense - the cave system is probably endless now. Tons of exposed riches to be found as you near the bedrock, but because the caves are so open, watch your step (and watch your back, too)!
