This mod contains 8 new world presets + 7 old/legacy presets!

Brand new world preset selection screen:

1st World Preset - Winter World

Many of you may remember this feature from the old Minecraft Alpha versions. Well it's back now with more challenging features! 

The whole world is buried in snow and in a never-ending winter cycle.

But now there is a new concern to watch out for. Introducing a temperature bar!

If you go under -10°C you start freezing. Swimming underwater, standing near a heat source, the daytime cycle and even the weather all effect your temperature. Also there are blizzards, so watch out!

2nd World Preset - Oneblock World

A true Minecraft classic. A singular block which goes through many phases, until you reach the end. Of course there are chests with custom loot tables, and random mobs for phases. Can you make till the end?

3rd World Preset - Skyblock World

Here you can choose from 3 versions. The original (no nether realm/sand island), 3x3 version (nether realm/sand island) and the newest version (nether realm/sand island). Be prepared to mine a lot of cobblestone!

4th World Preset - Skygrid World

Absolute chaos of random blocks. Original by SethBling.

In this world preset there are random blocks everywhere spaced by 2 blocks horizontally and 3 blocks vertically from each other. Random spawners and chests with random loot tables occasionally spawn. This may be quite CPU heavy!

5/6/7/8th World Preset - Challenge Worlds

There are 4 challenge worlds, each being very different from each other.

Challenge world 1

In this world you spawn at the very bottom of the world with a bonus chest! There is no bedrock and the surface is located at Y=320. If you die you respawn at the bottom, I'd recommend setting a spawnpoint with a bed. Good luck!

Challenge world 2

In this world you spawn in a random wooden structure. The catch? The world is nothing but only structures. All structures can spawn, no limits. Strongholds also spawn, so the game is beatable!

Challenge world 3

Here the world generation is normal. But your total health is cut in half (5 hearts max), food is cut in half (5 food icons), you can only use half of the inventory and you can't sneak (the cherry on top). Good Luck trying to beat Minecraft this way!

Challenge world 4

Here the chunk dimesions are 11x11, wide void gaps. Nice and simple. Hard to traverse and find structures. Good Luck on beating the game!

9-15 Old/legacy world presets

Here is the rest of the world presets. Minecraft already comes built-in with these. Default, Superflat, Large Biomes, Single Biome, Debug mode, Amplified and Floating Islands (which is in the game files, but it's not available in the default selection for some reason).
