THIS MODPACK REQUIRES A SPECIFIC VERSION OF OPTIFINE! (See download guide below)

Have you ever wanted Minecraft Survival to feel more immersive than it does? This modpack is for you!
This modpack changes the way Minecraft survival is played to make it much more challenging and WAY more immersive!
Either try your hand at building from the ground up in singleplayer or create a world for you and your friends to play in and
attempt to fight off the brutality of Mother Nature together!

Mother nature will not always work in your favor. You will die at some point.

Do not update mods in this modpack if given the option to and be careful when editing resource packs!

All Credit goes to the mod creators of mods in this pack. I did not make the mods, I simply put the modpack together and tweaked everything to make them work.

Known issues:

When playing on monitors above 1080p, the stamina bar will be offset from the center of the screen. This can be fixed by manually editing the stamina bar position in the mod config. (StaminaOfTheWIld)

When interacting with a bellows block, the game will freeze. For this reason, the bellows block should be unobtainable.

Stamina may sometimes start draining indefinitely. This is fixed by reopening the world or using a mount (for some reason).

The Rambutan fruit causes minor block lag when growing several trees in the overworld.

When using other shaders, the game will fail to render properly.

When placing the Blackboard, the game will crash.

Keep Inventory does not work properly.
