So here you can post suggestions for new dimensions and boss mobs.
So my first suggestion is for a new boss mob for the nether.
the King ghast. It should be a huge ghast and shoot giant fireballs
A new dimension suggestion. The moon.
on the moon, there would be no moon in the sky, instead there would be the earth in the sky.
when you are on the moon you would have leaping effects until you leave the dimension
